    Always On UPS Systems 2. GENERAL BLOCK DIAGRAM Figure 2.1 General Block Diagram Normal Operation: The rectifier/charger converts the supplied AC power into DC (bus) power, which is then supplied to the inverter and the battery charger. The DC to AC inverter then supplies continuous, noise free AC power to the critical loads. The inverter output is synchronized with the bypass AC power source provided that the bypass AC power source is within the specified frequency range.
