基于DSP的低压断路器校验电源的研制

Research on Verification Power for Low Voltage Circuit Breaker Based on DSP

利用电力电子技术的拓扑结构,采用基于DSP芯片的控制电路,研制了用于舰船热继电器及塑壳断路器校验所需要的交流电源装置。与传统电源相比较,不但电源装置的体积明显减少,而且输出的电流精度高,动态响应速度快,此外所研制的电源装置采用友好的人机界面,使试验过程变得简单容易,可以降低试验人员的劳动强度。

Using topology of power electronics technology and control circuit based on DSP chip, an AC power supply unit for checking ship thermal relay and molded case circuit breaker is designed. Compared with the traditional power. this power supply is small, the output current is accuracy and dynamic response is fast. It has a friendly interface, and makes the test process become simple and easy, which can reduce the intensity of experimenter.
