Beschreibung
Zusammenfassung:	The invention relates to a control method (4) for controlling the frequency of the input voltage of a DC-DC converter of a bidirectional electrical charger, operating in discharge mode comprising: a prior step of defining a set voltage value (VDC req), a step of calculating (40) a control frequency value (fsw(Omega)) of said DC-DC converter (12), obtained by inverting the gain of said DC-DC converter (12), as a function of an output battery voltage (Vbat), a set input power (Preq) and said set input voltage (VDC req); a step of fine adjustment of the DC bus by increasing/decreasing the frequency; and a step of applying the control frequency thus calculated to said converter. 本发明涉及一种用于控制双向充电器的DC-DC转换器的输入电压的频率的控制方法(4)，该充电器在放电模式下操作，该方法包括：-定义设定点电压值(VDCreq)的预先步骤；-根据输出电池电压(Vbat)、输入功率设定点(Preq)和所述设定点输入电压(VDCreq)来计算(40)所述DC-DC转换器(12)的控制频率值(fsw(ω))的步骤，该控制频率值是通过对所述DC-DC转换器(12)的增益进行反演来获得的；以及通过增大/减小该频率来微调DC总线的步骤。-将如此计算出的控制频率应用于所述转换器的步骤。
