Abstract
PURPOSE: To reduce the number of parts and improve reliability by sharing a part of the CVCF circuit (thyristor inverter type constant voltage constant frequency power supply) configuration to the load facilities requring the CVCF of a minimum of two difference frequency output.
CONSTITUTION: The stabilized non-power-failure systems UPS1-400 and 1-500 using a minimum of two CVCFs 11 consist of a single oscillator OSC 11a to drive the inverter 11D of a minimum of two CVCFs 11. As compared with the structure requring two OSCs 11a to a minimum of two CVCFs 11, the reliability of the OSC 11a can be doubled.
