Abstract In order to solve the problems of the slow searching resonant frequency and poor real-time performance of the frequency tracking in traditional induction heating power supplies, this paper proposes a modified all digital fixed-angle frequency tracking technology to meet the special demand of the induction heating power supply for pulsed eddy current thermography. First, the pulsed induction heating power system and operating principle were introduced. Then, the theoretical analysis of all digital fixed-angle frequency tracking technology was addressed in detail. The mathematical expressions of system steady and dynamic performance with system control parameters were established. The influences of the quality factor, initial frequency and stepped frequency on the dynamic performance of the system were further analyzed. Finally, experiments were conducted based on a pulsed induction heating power system to verify the performance of the modified all-digital fixed-angle frequency tracking technique. The simulation and experimental results show that this frequency tracking technique has the advantages of fast searching resonance frequency, good strong real-time tracking and good stability.

Key words： All digital fixed-angle-control frequency tracking technology series resonant inverter induction heating power pulsed eddy current thermography
