Abstract
A control method for controlling the frequency of the input voltage of a DC-DC converter of a bidirectional electrical charger, operating in discharge mode, includes: defining a set voltage value, calculating a control frequency value of the DC-DC converter, obtained by inverting the gain of the DC-DC converter, as a function of an output battery voltage, a set input power, and the set input voltage; finely adjusting the DC bus by increasing/decreasing the frequency, and applying the control frequency thus calculated to the converter.
