Abstract: Power conversion system includes a DC/DC conversion circuit, an energy tank, a switch, and a controller. DC/DC conversion circuit is configured to convert a first DC power into a second DC power and provide second DC power to a dynamic load. Energy tank is coupled to DC/DC conversion circuit. Switch is coupled between energy tank and DC/DC conversion circuit. Controller is coupled to energy tank and switch, and is configured to detect a first voltage of first DC power and a second voltage of second DC power to determine a change of dynamic load. When controller detects that first voltage is lower than a first preset voltage or detects that second voltage is lower than a second preset voltage, controller conducts switch so that a third DC power stored in energy tank is provided to DC/DC conversion circuit to compensate one of first DC power and second DC power.

Abstract: A method of inspecting power units applied to a plurality of power units is connected to a signal bus. The method is to disconnect the power unit having an output current from the signal bus, give a control command by a controller for raising the output current, measure the output current after the control command is given, and compare the measured output current with the target current value corresponding to the control command for determining an inspection result. The present disclosed example can effectively reduce inspection time and improve inspection accuracy.
