Abstract
A modular AC/DC power conversion module for power sources and loads and a method of driving the same is provided. When an AC/DC converter is electrically coupled to an external power source, a microprocessor is electrically energized by a buck auxiliary circuit, under control of the microprocessor, a DC/DC converter is activated for a certain time period, and then, the AC/DC converter is activated. Thereafter, an output voltage of the AC/DC converter is boosted, and an output voltage of the DC/DC converter is boosted accordingly. Power elements in the downstream side DC/DC converter are activated first, and then power elements in the upstream side AC/DC converter are activated, thereby an inrush current is suppressed. Once the external power source is connected, the buck auxiliary circuit will automatically reduce a voltage of the power input to activate the module. It realizes that the module will autonomously operate after being electrically energized.
