针对便携式核仪器采用电池供电、待机时间长等特点,提出了一种绿色模式DC/DC变换器设计,采用准谐振变频功率变换控制和同步整流等先进的电源控制技术,从各个环节降低DC/DC变换器运行功耗和待机功耗,提高系统效率.实验结果表明所研究DC/DC变换器达到了绿色设计目的,有助于延长电池使用寿命.

A green mode DC/DC converter was developed which suitable to the portable nuclear instrument which is powered by battery and is sometime at stand-by mode. Some updated control approaches such as pseudo-resonant type power supply control and synchronous rectification were adopted to make the DC/DC converter operate with low power consumption and high efficiency. The test results...
