Abstract—This paper presents the results from the research of output power control in a bridge converter with IGBT transistors loaded with a serial resonant circuit. The purpose of the research is operation of the bridge converter in mode of induction device. The mode of induction heating of metals have retroactive effect of the parameters of the resonant circuit on the power converter. The change of the parameters of the resonant circuit changes output power of the converter. Usually in the applications on the induction heating of the metal materials is required the converter to work with constant power. Therefore for working on the converter with constant output power at loads that change parameters of the resonant circuit, it is necessary to com-pensate the changes that cause a change in output power of converter. In the studies are used computer simulations developed in PowerSim and ELTA programs. Based on results from the researches is developed algorithm for man-agement by the output power of the converter with regulat-ing on phase difference between output voltage and the cur-rent through the inductor.
