This has become well known even in the cheapest UPSes since it requires advantage of parts already bundled. The key fifty/60 Hz transformer utilised to transform concerning line voltage and battery voltage demands to deliver two somewhat distinct turns ratios: A person to convert the battery output voltage (normally a many of 12 V) to line voltage, in addition to a second a single to convert the line voltage to a slightly larger battery charging voltage (like a various of 14 V).
