Abstract :
This paper presents an approach for variable switching frequency digital control scheme under dynamic transients in order to improve the dynamic performance of the DC-DC switching power converter. The controller varies the switching frequency of the converter, higher or lower than the steady-state frequency, during the transient as a function of error signal depending on the amount and type of the transient. Experimental results of a proof of concept prototype are presented in the paper to validate the controller.
