Abstract (en)
[origin: WO2019238405A1] The invention concerns a method (30) for controlling the input voltage frequency of a DC-DC converter (12) comprising a step (65) of calculating a control frequency value (F) of said DC-DC converter (12), wherein: - if the measured voltage (VDCM) is greater than said upper voltage limit (VDCR+eps), the control frequency (F) corresponds to said minimum control frequency (FRMIN); - if the measured voltage (VDCM) is less than said lower voltage limit (VDCR-eps), the control frequency corresponds to said maximum control frequency (FRMAX); and - if the measured voltage (VDCM) is between said upper voltage limit (VDCR+eps) and said lower voltage limit (VDCR-eps), the control frequency (F) corresponds to an average frequency (FMOY) calculated as a function of the difference between the setpoint voltage value (VDCR) and the measured voltage (VDCM), upper error values (eps) and lower error values (-eps) and maximum (FRMAX) and minimum (FRMIN) control frequency values.
