Interruptible power supply system for computer system, has interruptible double power supply system regulation unit to regulate double power supply system unit to be connected to or disconnected from DC converter based on comparison result

摘要

The system has a detection and control unit (22) to detect an operating status of a computer system (3) and to deliver a detection value. A comparison unit (24) compares the value and activation condition value delivered by a parameterizing unit. An interruptible double power supply system regulation unit (26) regulates a double power supply system unit to be connected to or disconnected from a DC converter based on comparison result. An independent claim is also included for a method to regulate operating power of a circuit of a DC converter and to control switching of the converter by a pulse width modulation control circuit to supply DC current to a computer system.
