摘要
介绍一种用于城市电动汽车的全桥DC/DC电源变换装置,并对该装置的电路结构和原理、控制方式作了较为详细的讨论和介绍。为保证正常工作,该装置设置了过电流、过电压和欠压保护及自启动电路。实验表明该装置的性能良好。
A novel DC/DC converter for the city' s tramcar is introduced. The structure,principle and method of the control circuit are discussed in detail. To ensure the mormal working of the circuit, some measures are taken, including the excessive current and voltage protection, low input voltage protection and self-building power. The experimental result has verified the good performance of the device.
