This paper presents a zero current switching predictive control strategy for a direct resonant converter which is part of a high voltage power supply. A voltage compensator is used to reduce the output distortion. The direct resonant converter and the voltage compensator consist of a three to single phase matrix converter supplying a series resonant circuit and an H-bridge converter, respectively...
This paper focuses on new control techniques for a direct power converter having a resonant tank on the output side feeding a rectifier. The application being considered is for HV power supplies. The objective of the control is to provide a stable output, with good supply current quality. Two predictive controllers are described, one based on the output tank dynamics and one based on the input filter...
This paper is concerned with the development of a new type of power supply for high power RF applications for CW operation. Losses are reduced by the use of zero current switching. This allows for a high operating frequency and minimised transformer and filter size. Preliminary practical results have been found to be promising, with design of the resonant circuit and isolating transformer being fundamental...
