A new implementation of high voltage, high frequency direct power converter

This paper presents an analysis of a predictive control and its digital implementation on a high voltage, ultrasonic resonant frequency (20 kHz) direct power converter (DPC). An extension of the input current prediction is proposed to enable the practical implementation of the control technique. Results from a simulation study and from a prototype converter are presented. Good correlation between simulation and experimental results measured on a prototype are shown, confirming the feasibility of the approach
