Abstract :
In this paper, a new quick response digital modified P-I-D control with flexible duty ratio for LLC resonant dc-dc converter in -48V DC power supply system and the transient response against input voltage step changes are discussed. It is revealed that the transient response of the input voltage is largely improved compared with the conventional method.
