Modeling and control of series resonant converter for high voltage applications

Most industrial processes that use electricity as a source of voltage or current, require power circuit for the control of its physical quantities. Power converters are a multi-site privileged in the control of high power systems. In this article we show that the series resonant DC/DC converter, which is a hybrid system. The SRC achieves an output DC voltage equal to n times the input voltage of the converter, the major disadvantage of this type of converter is the the stresses on the power components and Capacitor Charge Time. Furthermore, a control strategy for minimizing the no-load conduction losses is proposed and the transient behavior in case of load steps including output short-circuit is discussed based on digital simulations.
