The invention relates to a voltage converter and a controller thereof. A voltage converter includes a converter stage having a direct current to direct current (DC-DC) voltage converter, wherein the converter stage receives a first DC voltage and outputs a second DC voltage different from the first DC voltage. The voltage converter also includes a boost pre-stage having a boost circuit and a capacitor, where the boost pre-stage receives the DC voltage from the battery and outputs a boosted DC voltage as a first DC voltage to the converter stage, where the boosted DC voltage is greater than the DC voltage from the battery. In the event of one or more fluctuations in the operating range of the DC voltage from the battery, a boosted DC voltage that boosts the output of the pre-stage to the converter stage provides fault-resistant operation of the converter stage.

    本申请涉及电压转换器及其控制器。一种电压转换器包括具有直流到直流(DC‑DC)电压转换器的转换器级,其中转换器级接收第一DC电压并输出不同于第一DC电压的第二DC电压。电压转换器还包括具有升压电路和电容器的升压前级,其中该升压前级从电池接收DC电压,并将升高的DC电压作为第一DC电压输出到转换器级,其中升高的DC电压大于来自电池的DC电压。在来自电池的DC电压的操作范围中的一个或更多个波动的情况下,升压前级的输出到转换器级的升高的DC电压提供转换器级的抗故障操作。
