500 WATT INVERTER 12VDC TO 220VAC CIRCUIT SCHEMATIC DIAGRAM

Step up part of this inverter circuit using a transformer 12VCT/500VA in secondary and primary 0 - 220V. While the frequency is determined by the flip-flop which is set to 50 Hz.

Note:

•     Q7, Q8 and Q7x, Q8x require heat sink.


•     Output power of this dc dc converter is around 500 watts.


•     An optional 40A fuse can be added in circuit to the 12V supply line.


•     T1 can be a 12-CT-12V /250V/40A mains transformer.
