摘要:
为满足中低频(0.15~10 kHz)大功率感应加热和熔炼的要求,该文提出了一种电流源型半桥式晶闸管逆变器。探讨了其独特的双电流源电路结构的优势,比较了不同负载电流状态下的电路工作状态,通过数学计算得出直/交流等效电阻间的关系和输出功率比与频率比的关系曲线。通过功率输出特性分析可知,电路工作于负载电流连续状态且工作频率趋向理想状态时最适合大功率输出和功率调节。给出了选取电路参数的经典方法。根据该方法设计了一台样机,通过实验验证了理论分析及参数选取方法的正确性。
Abstract:
A current-source half-bridge thyristor inverter suitable for high-power induction heating and melting applications in the low and medium frequency(0.15~10 kHz) range is presented.The merits of unique double current-source inverter circuit are introduced.After comparing the work status in different load current states,the relationship between DC and AC load equivalent resistance is concluded individually by mathematic calculation and the relationship waveform between the output power ratio and the frequency ratio is obtained.The results from the analysis of power output characteristics show that the best way of power regulation in high power output state is to keep the circuit working in the continuous mode and the frequency tending to be that of the ideal mode.The circuit parameters selection strategy is concluded.A prototype is designed and the experimental results verify the correctness of the proposed analysis and parameters selection strategy.
