single-pressure stage

However, Due to the limitations of the single-stage converter, when the bus voltage is high and wide input voltage range, the single-stage converter is not suitable for multi-output low power switching power supply.

但是由于单级变换器自身的局限性，当电源母线电压宽输入范围时，单级变换器并不适合用作多路输出小功率开关电源的主功率拓扑。
