摘　　要：本文研制的高压逆变电源采用串联谐振式全桥DC-AC逆变电路,以Hall电流传感器、电压比较器和CD4046锁相环对负载电流实现了频率跟踪,使逆变器工作在谐振状态,文中重点分析了相位补偿和启动问题。通过实验验证了该方案的可行性。The frequency tracking of load current is implemented by the current transducer Hall. voltage comparator and CD4046 in this paper, The inverter operates at the resonant condition. Moreover this paper analyses the phase compensation and operation of starting. The feasibility of this method is verified by the experiment result.

关 键 词：频率跟踪 谐振 相位补偿
