When the input is 130/140/150/160v=> OUTPUT 300v (noisy,loud) Please tell me the reason behind it and what will be the cost to fix it Undervoltage protection circuit not working, it should shut down stabilizer instead of keeping it operating.
Since you're transforming, you can multiply the voltage as required by varying the turns ratio. So what really needs to be mapped are the input to output voltage spans. Vin goes from 140 to 280 which is a span ratio of 2.0. Vout goes from 200 to 240 which is a span of 1.2. This can most easily be worked out with logarithms. Log10(280V/140V)=0.3
It can Stabilize Mains voltage to around +/- 10% . It can be used for both 110V AC or 220V AC inputs with modifications. The Output is 220V AC. There is an overload, under voltage and over voltage trip circuit.
I've been looking for transformer-less AC-AC converter. How these converters works, what is the working mechanism and everything. I found a voltage stabilizer that is working very fine, that circuit is using just a big inductor and few FETs. I still don't know what is the technology behind this. Need help. Thank i
Hello i need Static voltage stabilizer circuit/documentation to make minimum 1kva stabilizer which could operate from 160v
Pin no. 3 is used for measuring scaled down AC voltage converted to DC. Digital IO pin is used as ADC pin as mentioned in some microchip doc which I don't remember. Relays are used to switch the tappings of the transformer based on read voltage. What is so difficult in understanding it ?
Hi everybody, I want help. I founded a 16f676 based voltage stabilizer circuit. but I cant find hex file for this pic. Can any one give me hex file for this uploa
It is reasonable to begin with a 2x step-up transformer, to cover the extreme job of converting 110 VAC to normal level. Then for those times when incoming mains AC is somewhere in between, you will need to find a way to reduce the voltage. You must either (a) reduce power going into the primary side, or (b) reduce power coming from the secondary,
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 (...)
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
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 (...)
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 (...)
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 (...)
Presented device is a 40 RGB diodes driver. The construction is quite simple, there are few elements on the board: stabilizer LM7805 + heat sink + voltage filtering capacitors microcontroller Atmega8 ULN2803
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 (...)
I need information about the taping of a tap changing voltage stabilizer transformer. I mean, for better regulation. I've done a rough calculation for the transformer. tapping is selected as: 180, 200, 220, 240, 260. and common.
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
i need static voltage stabilizer 1 KVA to 10 KVA , 90 V TO 290V /hex code /circuit diagram .contact me soon .
Hi all, i have currently work on a solar charger circuit which the circuit is shown below. But kinda not understand is,the zener diode is act like cut off voltage which cut off the charger voltage when the battery is 6.8v which is already full. The concept is when the terminal voltage is full which is (...)

hai, i want a circuit for automatic 3 phase voltage stabilizer using triac plz help me Thanks and Regards Grittin James
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
