Standby power supply with high frequency isolation
Standby power supplies (SPS) are widely used as power backup systems for critical electrical loads. A single phase SPS utilizing a high frequency AC link is studied. Use of a high frequency transformer results in a compact and light weight system. Energy loss introduced in the system due to the high frequency AC link is analyzed. Design of the control circuit, to obtain a sinusoidal output voltage with linear and nonlinear loads, is explained. The SPS is used as an active filter to obtain sinusoidal line current under normal conditions of the utility.<>
