ABSTRACT:
A half bridge converter having a pulse width control unit, a level regulating unit, a half bridge switch unit, an electricity converting unit and a feedback unit is disclosed. The level regulating unit receives a first DC electricity and boosting the first DC electricity to a working voltage level for forming a working electricity. The pulse width control unit produces a conduction cycle signal for controlling the half bridge switch unit to switch the working electricity to a conduction timing of the electricity converting unit, so that the electricity converting unit converts the working electricity to output a second DC electricity. The feedback unit draws a feedback signal from the second DC electricity to send to the level regulating unit for altering the voltage of the working electricity, so as to adjust the output of the electricity converting unit, thereby achieving voltage regulation.
