The digital phase-locked loop (PLL) system for the resonant voltage inverter with pulse density modulation of induction heating installations is developed. The proposed system for frequency determination uses the feedback signal on the collector-emitter (drain-source) voltage of the inverter transistors and on the output current of the inverter, and stores this frequency on the interval of zero output voltage. A study of the PLL system in different operating modes when changing the load parameters is presented. References 8, figures 6, table 1.
