Abstract :
Optimized prototype of 3-kVA/2.4 kW single-phase UPS system is proposed. Based on detail analysis, inverter loss distribution model is built, which shows three-level inverter is a good choice for UPS system. Moreover, other problems, such as method to reduce ripple current of DC-BUS capacitor, are also addressed.
