Anybody have a good and an efficient sinwave inverter 500 watt.
I also found around the change from AMD Single core CPU to Dual Core CPU Motherboards. The Earlier Motherboard had a Negative 5 Volts on the Power Supply, the -5V is not used on later systems. But if a newer 500 watt power supply with no -5v is fitted to a early Motherboard my Gigabyte with AMD 3000 CPU single core. All the Electrolytic caps on the
Hi Princess, A digital switching inverter will be about 80 percent efficient if the transformer is good and modern Mosfets are used. Then it draws 625W from a battery. If the battery is 12V then the current is 625W/12V= 52A(!) that cannot be used on a pcb nor on a breadboard. A very simple inverter has a squarewave output that cannot power many
You do not want to use an inefficient linear audio amplifier that uses 800W from the battery to make an output of 500W so that it makes 300W of heat. Instead you want an efficient Pulse-Width-Modulation circuit where it has Mosfets turning completely on and completely off so that little battery power is wasted by making heat. The PWM can be at a hi
i just want to build an inverter as mentioned above, i have already some components like irf 540 mosfets, two transformers extracted from 750va ups, can i use them to do the job. i had already some old 500 va ups. second can i convert them to build an inverter around 500 watt. if so, what are the changes required to be done
Hi, I have to design a 40 watt Flyback transformer. SPECS ------- 1. Primary 230 VAC 2. Secondary 12 Volt 3. Pout = 40 watt 4. Creepage distance = 6.4 mm 5. Primary inductance = 500 uH 6. Secondary winding = sandwhiched inside the 2 primary halves QUESTION 1 ------------- Which core is best to keep the Leakage inductance (...)
Calculate a choke inductor with reactance greater than 500 ohms at working frequency (if your impedance is 50 ohms), and also calculate the choke wire thickness for DC current consumption greater than 1A. The decoupling caps part of the bias tee should have very low reactance at working frequency. Place more in parallel for wideband response.
hi i want to drive 24volt dc motor (500 watt)whose current rating is 20amp. may any body suggest me proper driver circuit
hi i have used 3+3 mosfet bank in my first stage of the inverter i.e dc to dc converter stage, so my question is how can protect my mosfets from burning? what protection circuit or components should i use along with the mosfets so that it does not burn in any case? i have made 3 times the mosfet banks but ,,after some time it get p
hello guys, please help me out in designing a 500 watt solar based inverter.. as i am new to this field need your guidance, please share any schematic based on proteus or pspice based design.. wana refer thank you regds md shb
I know the wattage of the coil is 200 watt and the resistance of the coil is 500 ohm and it works on 24 VAC The numbers don't go together at all. A "coil" (solenoid valve, relay or contactor coil) will expose an AC resistance larger than the DC value. In any case, the current for 24 VAC can't be larger than the respective DC cur
for a 220v output VFD and space vector the bus should be 300 to 350v for 380v version 500 to 600v if you use the motor in delta configuration you just need to rectify the 220v ac and put 1uf per watt electrolytic capacitor on DC link. (400V) for instance a 2200w motor drive needs 2200uf/400v bus capacitor. don't forget the inrush current limiter
Can be done, needa 2 switch flyback (500/600V fets) or a 800/900 V mosfet for single switch. We have done 300W flybacks with 10 ADC continuous out
Hye.. can somebody give me circuit diagram and ic programming for inverter 12v dc to arround 240v ac, power output arround 500 watt, pure sine wave. I really appreciate ur help... plzzzz..... i want to finish my project :sad::sad::sad:
Hi all! A friend of mine has this Nokia gadget that has 8 digital outputs that can put out 6-30 VDC. I was asked to help design and build a circuit/s to turn each output into 220-240 VAC to make 8 outputs, each capable of supplying a 500 watt device. I've been looking at inverting circuits (like these:
hi to all i have made this little uhf modulater from old vcr and only gives fiew meter i need little more power not more than 1 watt or less 500 mw is enough good i need to transmit and increase its power rf output to 1 or more km with external aerial antenna what kind of amplifier transistors bfr 90 91 96 bfq68 do u gave me or such a design wi
need 500 watt ac voltage stabilizer
can anyone share a 500 watt sine wave inverter schematics with PCB layout, component layout and source codes if any in your collection which you have tested and worked. i il be greatful . Regards.
Hello there I am asking about some help. I am doing a project wich supposed to oscillating current about 25 kHz. L1 = L2 and i replace l3 with a 100watt lamp. It works. When i change the lamp with an 500 watt lamp( the load will have about 1800watt ). The circuit doesn´t work and blow up the igbt. Any one help me? Why igbt (...)
Hi Admin/Moderators and ALL members, Please help me to design DC/DC converter that have power for 3500 watt and use for wide range input DC. I have input for 100V - 500 V DC and the output is 12 V or 24 V DC Thank a lot for your help
14MHz is assigned for radio amateur use. For emmiting 500W on that frequency you will need licence and only for purpose of amateur communication under allowed modes of operation. If you attempt to do this illegaly, it won't be long before someone knocks on your door. If you have problem with radio amateur in your neighborhood, you should try to
Hello. I want to design 500 watt coaxial termination at 3GHz ~ 4GHz. How to select heat sink? And I can't find 500 watt termination. Please let me know them and new idea. Thanks in advanced.
What are the difference?? VA = 500 W = 350 ? thanks
Yes, try small emitter resistors. And please wear safety glasses! Once upon a time, a friend of mine was troubleshooting a 500 watt switching power amplifier. I handed him my safety glasses. He asked "do I need these?". I replied "just in case". He put them on. A few minutes later the amplifier blew up and pelted him in the face with flying F
Given the carrier as: c(t)=cos(2*pi*fc*t) where fc=800kHz m(t)=sin(2000*pi*t)+5cos(4000*pi*t) and the AM signal s(t)=100cos(2*pi*fc*t) being fed to a 50Ω load... Are the following correct: Carrier Power Pc=100?/2=5000W and Total Side band Power= 100?/4+500?/4=62500W I got the above results... Can someone please tell me if
