need 500 watt ac voltage stabilizer
Hi, I want to design a voltage stabilizer for home purpose. although they are available in markets but i want to design for learning purpose as well as using good material because local manufactures used sub graded material (for winding etc). i would be appreciated i some one tell me the basic behind (calculation , equations etc)it as well

tapping is select as - 137 . 200 . 240 . 290 This is for a specific circuit with a specific relay driving algorithm. It would help if you discussed when which relay is turned on at which voltage or a similar table. I need information about the taping of a tap changing voltage stabilizer trans
please help me in finding a circuit for an AC voltage regulator for household purposes.voltage fluctuations are frequent in our inorder to rectify the problem i need a 230 voltage regulator circuit...
similar circuit, although easier to read, in the attached. I am assuming it is a temperature compensation circuit. The proper gate voltage to the LDMOS fet wants to vary slightly over temperature. The 7805 if fixed voltage output (5 volts) over temperature, but if you float it slightly off of ground with a transitor (...)
try this hex file hi, this hex file is not working properly. I checked it, in real time simulation. I think you write this code with CCS compiler. Only timer,over and under voltage section is ok. And stabilizing section is not working. All 3 relays become off at same time, when adc volts are 1.6v. And become on together, agai
Hello Dear psyduck At first step about sine wave inverters i should tell you , that , it is not good way for go . So i can describe it's correct and usual way : you should make an H bridge to obtain Higher voltage DC with HF transformer , and then you should design an H bridge without transformer and with SPWM , ( last stage made with Constant
I would say a voltage stabilizer was used up to 1KW and at higher powers its an AVR. Frank
One more comment about the posted differential voltage stabilizer. You'll notice that it involves a transformer, although with smaller power. You should know if it complies with your initial statement not to use transformers? A straightforward design uses H-bridge PWM converters at in- and output with a DC bus inbetween. But the effort is most l
1. Use transformer to step down from 230rms to 5V rms and then u can send it to ADC after clamping the mean valuw of voltage to positive side. This will also provide isolation from line and use surge protection at transformer secondary to minimize hard to ADC and circuit. Transformer is best and mostly used solution. 2. Instead, u can go for triac,
You need more then two steps for voltage regulation between 110V 240V. With two steps you will have high voltage difference, I don't think that your devices will be happy. Use more steps, for fine regulation. Search forum I post project circuit with LM324 voltage stabilization somewhere, and maybe you find some others (...)
There is no 'accuarcy' they are both using taps on an autotransformer to step up the voltage by different amounts. The output can only be whatever comes from the transformer so it depends on how many taps you use. The circuits are essentially the same, one using mechanical switching, the other electronic switching. Both will work, the mechanical o
It goes this way: When ps is swiched on, both BC182 and BD241 are fully conducting because 1K resistor connected to base of BC182. Transistors are darlington connected. Load current is flowing through BD241 and 0,35 ohm resistor. At current limit (2A) the voltage drop on 0,35 ohm is sufficient to open second BC182 (most right). BC182 through curr
Here are the questions to understand... Explanation IV char.. temp dependence on VI char... junction capacitance..break down voltage and its application types of diodes and its applications(multiplier..) make transistor from two diodes... material use in making it area cover by the LED,IR etc...(may be asked)
Using a classical linear stabilizer circuit won't help you. The 7805 voltage regulator dissipates a lot heat. Try to use a DC-DC step-down convertor instead. See for example LM2575, LM2576, LM2596, LM2678, LM2679. Some details here
Hi, I am planning on building a filter/regulator in preparation for my project car. I am still in its first stage, which is constructing a filter/regulator, or voltage stabilizer for my car's electronics. There are already a lot who have added a set of parallel capacitors between the alternator/battery to ground terminals and according to th

hi, i have a single phase power supply coming to home & several welding shops are there in my locality using the same line so EMI noise & minor voltage fluctuation are there on the power supply when they are working which is affecting computer. ups seems to jitter (avr) almost all the time due to this. can i do something to solve this issue
Your circuit works like a stabilizer with an output voltage (appr.) 6.8 + 0.7 v. Use a bistabil control element to make a permanent cut off.
Hi, Prabrahim I suppose it is necessary to add 12V integral stabilizer of the voltage after diode bridge and filterring capacitor C4 must be not electrolytic
Ive been doing some looking around, could I use phase control operation with a triac+diac setup and reduce/increase the phase for 230/110V? The solenoid when connected to 110V draws around 450mA, if I use 230V (roughly double V) and half the time the solenoid is on for via the traic is that likely to give a average of about 450mA at 230V? T

hi... i have made voltage stabilizer and circuit is successfully tested on vero board many times... but when i try the same circuit on pcb it started giving abnormal behavior... sometimes it works fine and sometime not ok.. even if i plucked pic off and then again put it on socket it stops working accordingly... can sumbody (...)
Hi All, I want to ask a question. I am confused about it. I made a low power application circuit that work with thermocouple with rectifier at the beginning then the booster and then the voltage stabilizer IC to make the output constant at 2.7. The 2.7V drive micro-controller. Now at 2.7 Volt I have to check the power of the (...)
It depends on stablizer design. If the designer has implemented under/overvoltage, the stabilizer will simply turn off the output power. If the stabilizer doesnt have undervoltage protection then if the input voltage decrease below 160V the output voltage will decrease below 200V (...)
Is it an electronic stabilizer or a ferroresonant transformer ? Could you post brand and model ? Well the stabilizer in the asian world is not ferroresonant transformer (also called CVT in our country : constant voltage transformer) Essentially the name stabilizer is a slang in local dialect for a device that has
Dear friends , I m working on a project : zero voltage switching ...relay based stabilizer..... Please suggest any design challenges faced.... So far i have to sense the ac mains voltage ...and based on the voltage , i have to switch the tapping of autotransformer through relay.. Now i am planning to use the zvc (...)
The name of the circuit that could help you is: “VFO stabilizer”. This is not a PLL, is just a cheap idea, to stabilize the frequency of a variable frequency oscillator (invented by radio amateurs back in 70’s). The signal from a stable on-board crystal oscillator and a sampling of the signal from the VFO are both processed thr
post the circuit then only we can check with circuit, mostly microcontroller based stablizer read ADC value of the input volt and drive the relays as programmed according to the voltage level
Hello, dear friend! You will find that even the most sophisticated simulation is some times far from true!This can be due to wrong inputs or the program is not considering all the factors. The magic is to try to build it yourself. Maybe you know that this supply uses parametric stabilization, which is not so efficient. To increase the output voltag
The pass device in this regulator is made up of an NPN in standard regulator topology. In this circuit, the zener diode is used to stabilize the base voltage of the NPN transistor, which carries the load current. The base-emitter junction behaves like a diode. In this way in the emitter we find Ue=Uz-0.7V. (A base current Ib flows only when the
This power supply has two outputs, main output adjustable by the microcontroller in range from 0,3 to 29V 4,8A and the auxiliary 3,3/5V 0,8A (not monitored) available from one socket. Both stabilizers are step down type and have s
The power supply consists of two separate modules: control part with the stabilizer and the transformer. In this project there isn't no power transformer, so its total weight is less than 4kg. The transformer has
