Abstract :
A simple technique is proposed to implement the current-share method for peak-current-mode controlled power supplies. By using two PWM control ICs in each paralleled unit or a power system, the requirements of current sharing and galvanic isolation can be both satisfied. Two 100W peak-current-mode controlled flyback power converters are paralleled for verification. The experiment results reveal that current sharing is achieved with stabilized output voltage.
