Description

Circuit diagram like in Figure 1. is Circuit Diagram Sinewave 3KVA Inverter Using SG3525 and NE555. According Electronic Circuit Project site that publish this circuit describe that each emitter junction of the respective BJT pair will hold 10 mosfets...therefore you will need only 4 BJTs in all.

1,ok if i may get you right, since you said 4 BJTs, 2 on leg A, 2 on leg B, THEN another 2 BJT from the output of PWM, right?

2, am using 24 volt battery hope no any modification to the BJT collector terminal to the battery?

3. i have to use variable resistor From oscillator to control the input voltage to the mosfet, but i dont know how i will go about the voltage that will go to the base of the BJT in this case, what will i do so that i wunt end up blow up the BJT?


yes 4 BJTs for the buffer stage, and two for the PWM driver.

24V will not harm the BJT buffers, but make sure to use a 7812 for stepping it down to 12V for the SG3525 and the IC 555 stages.
