12V TO 220V POWERFUL SMALL INVERTER 500WATTS

how to make power small 500watts high frequency inverter circuit #circuiters #ece #college #eee #electrical #project
hello guys in this video I am going to make small high power inverter ,the inverter size is very small and powerful,i am using sg3525 pwm ic ,this ic is quite popular and cheap in market,in this video I am using smd mosfets you can also use normal mosfets(like z44,irf3205) ,this circuit produce 41k hz square wave ,in this circuit i have fixed the variable resistance to control the output frequency ,in my case the MOSFET is very cool at 300watts but i am not shows that experiment in the video ,if you face any problem like no load current is too high then connect the circuit in series connection to the bulb like this( 04:39 )and rotate the variable resistance untill the bulb brightness is decrease, most of the components i took it from the old SMPS , this circuit is good but not all the time because this circuit has no feedback circuit to control the output voltage and also the output wave form is square wave in my future video i will make an perfect inverter with feedback circuit
