Abstract
In order to simplify the structure of laser diode drivers , improve the power conversion efficiency and dynamic response of the output current , a 2kW single-stage switching power supply was developed with interleaved single ended forward conversion.Static characteristics, dynamic characteristics and power conversion efficiency of the laser diode driver were tested and analyzed .The results show that the power conversion efficiency is up to 85%.The rise time and fall time of output current in range of 0A~100A is 1ms.The ripple coefficient of output current is 0.04%when output current is 100A.Compared with laser diode driver with two-level cascade structure , the power conversion efficiency of the power supply was promoted .The dynamic response of output current is so rapid that the power supply meets requirements of laser processing .关键词
