一种实用的大功率全桥ZVZCS变换器的设计

摘要

It is very common that the power consumption is too high and the efficiency ratio is too low in the field of the current full-bridge ZVZCS converter, thus a practical circuit topology is designed and its working process is analyzed to solve the problem. The converter lead pipe can achieve a zero voltage turn-on and turn-off by using MOSFET, and a zero current turn-on and turn-off lagging by using IGBT. By analyzing the relevant waveform of the converter , the correctness of the converter designed is verified. Through installing the electric power, the converter reaches the function required and meets the needs of market.%针对当前大功率的全桥ZVZCS变换器存在功耗过高，实用率不高的问题，提出一种实用的电路拓扑结构，并对该电路拓扑进行了简单的分析。该变换器超前管采用MOSFET，实现了零电压开通和关断，滞后管采用IGBT，实现了零电流开通和关断。对变换器主电路各参数进行选定后，通过采集的相关波形，验证了设计的变换器的正确性，将该变换器应用在电力操作电源上运行，性能优良，满足了市场要求。
