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.
- 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.
