摘要

微型电动汽车家用太阳能发电系统是实现可持续能源社会的重要技术之一。本文的目的是演示连接太阳能板和直流母线之间的高性能数字控制相移全桥变换器。由于部分产品的家用蓄电池和电动汽车蓄电池的电压在72V左右，所以样机的输出电压在70V到84V之间调节。样机输出功率为8kW，符合家用太阳能发电的一般功率。因此，原型机实现了高达94%的功率效率。当负载阶跃变化为0A ~ 100A时，输出电压波动小于1%。

72V DC bus output full-bridge converter in solar power system for micro EV

A home solar power system for micro electric vehicles (EVs) is one of the important technologies to realize a sustainable energy society. The aim of this paper is a demonstration of a high performance digital control phase-shifted full-bridge converter connected between solar panels and the dc-bus line. Since the voltage in a home storage battery and EV battery is around 72V in some products, the output voltage of prototype is regulated from 70V to 84V. The output power of prototype is 8kW conforming with a general power amount of home solar power generation. As a result, the prototype achieves up to 94% power efficiency. Moreover, the output voltage fluctuation is less than 1% when a load step change is from 0A to 100A.
