N2 - In this paper, a digital and analog hybrid control of multiphase power-modules with low output-voltage and high output-current are presented. The topology of each power module is a current-fed push-pull converter. The front stage is a buck converter which is used to regulate the output voltage and the rear stage is a push-pull converter with the electrical isolation and voltage step-down function. The advantages of the hybrid controllers are fast load transient response, flexible control, high reliability, and high power density. Finally, three paralleled power-modules with 2.5V/150A output is implemented. Experimental results show that good output-voltage regulation, current-balance, and high efficiency can be achieved.
