Abstract
Basic methods of frequency control voltage-source series-resonant inverter induction heating equipment were considered. A comparative analysis of a phase-locked loop (PLL) systems and approaches in design them for voltage-source seriesresonant inverter were presented. Analytical expressions for determining an optimal current switching transistor of voltagesource series-resonant inverter, time of transistor’s recharge parasitic capacitances with snubber’s capacitance, as well as the delay time between the control signals of the transistor, and time which corresponds to the phase shift between the input signals of the phase detector PLL are established.
