摘要
针对超高频感应加热电源电路中寄生参数和开关损耗两大难点,提出了一种能够吸收电路中感性与容性寄生参数、开关器件工作于零电压开关方式的双管超高频变换器。从而解决了寄生参数引起的电压电流过冲和开关损耗大的问题。由于输入端串入了高频电感,该变换器还同时具有电压型和电流型逆变器的优点,两只开关之间不需要导通死区时间,因而更加适合于高频工作。该本分析了电路的工作原理,并给出了1MHz频率下电路工作的仿真与实验结果。
A novel bi-switching super high-frequency converter is proposed. The converter is capable of absorbing the inductive and capacitive parasitical components in circuit for induction heating power supplies. All switch devices operate in zero-voltage soft switching mode. The problems of high voltage and current spikes caused by parasitic inductor or capacitor oscillation, and huge switching loss in super high-frequency operation, which are troublesome in super high-frequency circuits, can be solved. Moreover, as a high-frequency inductor is inset in the input, this novel converter shares the benefits of both voltage-type and current-type inverters simultaneously, and the dead-time between two switches does not need, therefore, this converter is suit to operate in high-frequency conditions. The working principle of the converter is presented in this paper, simulation and experimental results operating around 1 MHz frequency are given.
