Modularized power supply
First Claim
1. A modular power supply, comprising:
- a plurality of power supply modules, each power supply module having a power circuit coupled to a power input of the module for receiving an input power current and for producing an output power current at a power output of the module, said power circuits each including at least one switching element for switching the respective said input power current or the respective said output power current, said power circuits each further including a control circuit input that is coupled directly to the respective said switching element; and
a system control circuit for controlling said power supply modules, said system control circuit having a control circuit output bus for connecting to the respective said control circuit inputs of each of said power modules and providing a respective control signal to each said module for directly controlling the respective said switching elements in such manner that said modules may be controlled independently of each other.

Abstract
A modular power supply. A plurality of power supply modules and a system control circuit for controlling the power supply modules are provided. Each power supply module has a power circuit coupled to a power input of the module for receiving an input power current and produces an output power current at a power output of the module. The power circuits each include at least one switching element for switching the input power current or the output power current of a module. The power circuits further include a control circuit input that is coupled directly to the respective said switching device. The system control circuit includes a control circuit output bus for connecting to the control circuit inputs of each of the power modules and provides a respective signal to each module for directly controlling the respective switching devices.
