Power supply load balancing apparatus

摘要

A power supply load balancing apparatus comprises a voltage converter capable of accepting a plurality of supply voltages and converting a selected supply voltage selected from among the plurality of supply voltages to an output voltage, and a controlled rate switch. The controlled rate switch is coupled to the voltage converter and capable of selecting from among the plurality of supply voltages. The controlled rate switch applies switching among the plurality of supply voltages at different rates to unambiguously apply the selected supply voltage to the voltage converter.
