AbstractA constant frequency diode-clamped series resonant power converter (CFCSRC) is proposed as a solution to problems associated with frequency-controlled resonant converters. This converter has two resonant frequencies, and control is achieved by varying the relative time per switching cycle spent at each resonant frequency. Two zero-current-switching (ZCS) modes are examined and plotted in the output plane. Operating and mode boundaries are found and also plotted in the output plane. The output equation for the main mode is shown to be hyperbolic. Peak voltages are shown to be less than or equal to the input voltage, and peak currents are shown to be less than those of the frequency-controlled diode-clamped series resonant converter over a large operating range. A design procedure is given in the form of a design example. Data from a prototype converter is plotted with theoretical data in the output plane and good agreement with the theoretical model is obtained.
