What is Pumped Storage Hydropower? Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into ...

The computer power supplies as well as commercial units normally have to ride through at least one cycle of input sine wave, which is 16 ms in U.S. and 20 ms in Europe. The PFC boost provides DC-link voltage (Vdc) which is higher than the peak of input AC. In modern computer PSU, this voltage is typically 375-400 VDC.
