Embodiment example
[0138] Figure 14 Shown is a detailed circuit implementation of one embodiment of the invention. Such as Figure 14 As shown, a full bridge inverter is used as the power converter in the power control capacitor circuit 140 of the Boost converter. The output terminal of the full bridge inverter (for output voltage Vaux) is connected in series with the output capacitor Cout and then connected to the load Rload. The full-bridge inverter generates a voltage Vaux to offset the AC component of the voltage Vac1, thereby generating only a DC voltage across the load Rload. It should be noted that the capacitor Ca is part of the input LC filter of the full bridge inverter. The value of the capacitor Ca depends on the switching frequency, and the value of Ca does not depend on the low frequency component to be compensated by Vaux. The value of Ca is smaller than the value of the output capacitor Cout in most cases.
[0139] The input voltage Vin_aux of the full bridge inverter can be...
