Powerful 500VA Inverter SINE from UPS

Today, I will convert 1 UPS square waves, with a power 500VA - 300W. It uses IC SG3525 to boost 12V to 310VDC, use pulse transformer, then the H-bridge uses 4 mosfet IRF740 will convert 310VDC into AC220V, I have removed the old MCU and replaced it with the new MCU PIC 12F683 . It is responsible for controlling H-bridge by PWM to convert 310VDC to 220VAC sine wave.
