An adjustable high voltage variable-frequency microwave oven power supply was described,in which a LLC resonant converter with a voltage doubling rectifying circuit output end was used as main circuit topology,and a L6599 chip was used as control core.The DC gain of the converter was deduced by using the first harmonic analysis method,and the corresponding curve was drawn by using MATLAB software.The influence of various parameters on the LLC resonant converter was discussed,and then the parameters were optimized.Finally,the main circuit of the designed microwave oven power was simulated by PS...
