Autonomous uninterruptible power-supply apparatus
This invention relates broadly to a power supply apparatus, and in particular to an autonomous uninterruptible power supply apparatus. The purpose of an uninterruptible power supply (UPS) is to protect critical electrical loads from transient or steady-stage outages or disturbances in the primary power source. The basic configuration of a typical, commercially available, uninterruptible power supply is comprised at a minimum of a standby battery and a battery charger and may also include an inverter for AC applications. Systems of this type can be found in most computer installations and laboratory systems that cannot tolerate even momentary disturbances of input power. This document describes an autonomous uninterruptible power-supply apparatus utilizing a digital-processor unit as a control and monitor unit to measure and control input and output parameters in the power supply. A battery charger is utilized to maintain the voltage and current levels with the backup battery supply source which powers an inverter unit that converts the DC power to an AC output.
