【Abstract】 This paper describes the necessity and switch mode of motor driven by from the inverter power to power supply, and introduces the principle of components of a switching device. The experimental results indicate that this switching device can better achieve the synchronous switch mode control from the inverter power to power supply with the smooth current, simple structure in switching device and high working reliability.更多还原
