Power Electronics

Power electronics is the technology used to convert the power obtained from a power plant or renewable energy source into a usable form for end users. Substation equipment and EV drive systems are also made possible by power electronics technologies. Substation equipment is essential for a stable power supply. EV drive systems convert electrical energy stored in batteries into the power that drives EVs. This page looks at some examples of power conversion technology and EV drive system design technology.
