针对倍频电源的主电路拓扑结构，研究分析一种分时控制与密度调功相结合的分时一密度复合功率控制策略，并应用复杂可编程逻辑器件CPLD和数字信号处理器DSP的协调工作来实现分时一密度复合调功、频率跟踪控制及保护等，以MOSFET为主控器件，采用倍频的方式实现700kHz／10kW高频大功率感应加热电源。(In view of the main circuit topology of frequency doubling power supply, a time-sharing and one density hybrid power control strategy is studied and analyzed, which combines time-sharing control and density power regulation. The coordinated work of complex programmable logic device CPLD and digital signal processor DSP is used to realize time division and one density function, frequency tracking control and protection, and MOSFET is the main control device and frequency doubling is used. Now, 700kHz / 10kW high frequency and high power induction heating power supply.)
