Identify the principles of operation of uninterruptible power supply (UPS) systems, focusing on double conversion and offline/standby/backup types. The traditional UPS is now referred to as a “double conversion” UPS. The AC input power is rectified into DC. The DC feeds an inverter which provides the AC output. The DC bus is also connected to batteries. It is called double conversion because the first conversion is from AC to DC and the second conversion is from DC to AC. The inverter creates the output waveform to match the bypass input. Because of this, the static bypass switch may be switched between inverter and bypass seamlessly.
