1. A method for controlling a frequency of an input voltage of a DC-to-DC converter of a bidirectional electrical charger that is connected to a battery, operating in battery-discharging mode with a duty cycle of 50%, said method comprising:
defining a setpoint input voltage value at an input of the DC-to-DC converter, inputs and outputs of the DC-to-DC converter being defined with respect to a battery-charging mode;
calculating a control frequency value for said DC-to-DC converter, said control frequency value being obtained by inverting a gain of said DC-to-DC converter, according to an output battery voltage, an input power setpoint, and said setpoint input voltage value; and
applying the control frequency value to said DC-to-DC converter.
