机车空调逆变电源设计

Design of Inverter-Power of Air-conditioner of Locomotive

本文讨论的是机车空调逆变电源系统的设计与研究。该电源系统主要是由DC/DC的BOOST升压部分和DC/AC三相逆变部分两部分组成。DC/DC部分所得直流电压通过DC/AC部分逆变成三相交流电,供给空调机组工作。同时,为使电源系统能更可靠的运行,也设计了相应的故障检测、保护等辅助电路。

Firstly, at the base of understanding and comparing the theory of switch-power, consulting work of others, bring forward the entire project of power system used in air-condition. The project consists of two parts： DC/DC part and DC/AC part. Secondly, the DC/DC part is designed in this dissertation. This part mainly adopts switching-power supply technology. Thirdly, the DC/AC part is described in this dissertation in which the AC voltage is transformed to DC voltage. This AC voltage supplies air-condition to work and modulate the temperature. Then, Experiment and analysis the results of the experiment.
