How to choose transformer based and Transformer less UPS
UPS system has become vital component for managing critical downtime of all industrial applications and guarantee the power continuity. The question is what topology UPS has to use – · Transformer based UPS · Transformer less UPS Transformerbased UPS are basically a technology where transformer is inbuilt at the output of UPS and provides galvanic isolation between the rectifier and output of the UPS, that helps in connecting two sources to the rectifier and bypass without any disturbances to straight to the earthing system. The rectifier and the bypass inputs are the two AC inputs UPS has which can be connected as a form of common input inside the UPS. Normally, when main are available, the normal power flows via rectifier, inverter and transformer to the output which supplier critical load which is termed as “Double conversion mode”. In this mode, the battery is const...
