WebClass-E diode or FET-based rectifiers are finding interest for efficiently recovering power from an incident RF signal in wireless power transmission applications (WPT). For example, a recent synchronous rectifier in 0.13 Pm CMOS technology at 2.4 GHz [15] is designed to be employed in wireless sensors that do not require batteries. WebRotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.
