Description
Summary:This paper describes a universal sinusoidal modulator developed primarily for the multilevel cascaded H-bridges converters. The modulator was implemented as a FPGA entity and its versatile features allows it to be easily reused in various topologies based on H-bridges. This includes the control of the H-bridge resonant converters by pulse frequency modulation so that it is well suitable for the power electronic transformer topologies. The modulator's performance is illustrated on a laboratory prototype of seven-level active front-end.
