摘　　要：随着可再生能源技术的发展,需要性能优良的三相整流系统,将风力发电机等清洁能源系统产生的交流电转换为直流电进行储能或供电。针对此问题,提出了一种适用于风能以及太阳能的整流系统设计。该设计方案以三相整流为核心,通过变压器隔离降压,给三相全桥不可控整流电路供电。接着经过boost升压电路将输出的电压升为50 V,再经过buck降压电路将电压降为36 V,最终得到稳定的36 V电压输出。经测试,该方案表现出的平均负载调整率为0.184%,平均电压调整率为0.228%,为满足现代电子设备对直流电源的需求提供了新的思路。With the development of renewable energy technology,a three-phase rectifier system with excellent performance is needed to convert alternating current generated by clean energy systems such as wind turbines into direct current for energy storage or power supply.To solve this problem,a kind of rectifier system design suitable for wind and solar energy was proposed.The design scheme takes three-phase rectifier as the core,and provides power to three-phase full-bridge uncontrollable rectifier circuit through transformer isolation step-down.Then the boost circuit increases the output voltage to 50 V,the buck circuit reduces the voltage to 36 V,and a stable 36 V output is gotten finally.The test shows that the average load adjustment rate is 0.184%and the average voltage adjustment rate is 0.228%,which provides a new idea for the demand of modern electronic equipment for DC power supply.
