| 摘 要： | 基于经典全桥零电压零电流开关(ZVZCS)变换器拓扑,采用数字信号处理器(DSP)进行控制,提出了一种新型的移相PWM波形产生算法。结合IR公司最新推出的集成驱动芯片IR2304,通过对传统驱动电路增加两个无源元件,设计了带有负电压关断的硬件驱动电路,克服了IR系列不能产生关断负电压的缺点。实验验证了新型算法的正确性和驱动系统设计的可行性。

| Abstract: | Based on the basic Full-bridge Zero-Voltage-Zero-Current Switching (ZVZCS) converter,using digital signal processor,a novel arithmetic is presented in this paper.It uses DSP to create phase-shift Pulse-Width-Modulation wave. Ultilizing the new generation driver integrated circuit IR2304 which is released by the Unites States IR company,based on the research of the conventional driver circuit,the paper optimizes the circuit by adding two passive devices.The improvement makes IR2304 to produce negative bias v... |
