ABSTRACT:
A controlling device for conversion of DC power to sine wave AC power, including a boosting circuit, a sine wave generating circuit, a PWM wave generating circuit, a drive module, an MOSFET output circuit, a filter circuit, a protection circuit and a feedback circuit. The MOSFET output circuit outputs PWM wave by all-bridge type, whereby the safety in operation of the circuit is ensured and sine wave AC current is output.
