Power supply system with multiple power supply units

Abstract

A power supply module comprises a voltage input adapted to receive an input voltage, a voltage converter configured to convert the input voltage into an output voltage, a voltage output adapted to receive the output voltage, and a controller. The controller comprises a voltage trim input configured to receive a voltage trim input signal from a master power supply module, a voltage trim output configured to output a voltage trim output signal to a slave power supply module, and a drive control circuit configured to generate a converter control signal based on the voltage trim input signal. The converter control signal is configured to control an operation of the voltage converter. The controller further comprises an output signal generator configured to generate the voltage trim output signal based on the output voltage.
