A Single-Switch Bidirectional AC Chopper-Based Electronic Load Controller for Pico Hydropower System

This paper proposed a simple electronic load controller (ELCr) for a pico hydropower system. The electronic load controller is used to regulate the output power of hydropower generators, thereby maintaining the output voltage and frequency at desired values. Conventionally, the diode bridge rectifie...
