Power electronics is the applications of solid-state electronics for the control and conversion of electric power.
Power electronic converters - to modify the form of electrical energy (voltage, current or frequency).
Power range - from some milliwatts (mobile phone) to hundreds of megawatts (HVDC
transmission system). With "classical" electronics, electrical currents
and voltage are used to carry information, whereas with power
electronics, they carry power. Thus, the main metric of power
electronics becomes the efficiency.MORE
