摘要
The digital phase-locked loop (PLL) system of the resonant voltage inverter with pulse density modulation for induction heating installations is developed, which improves the switching modes of transistors under a wide range of load parameters. The proposed system for frequency determination uses the feedback signal on the collector-emitter (drainsource) 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. © 2022. All Rights Reserved.
