Abstract:
1. An optically powered MEMS gate driver, comprising: a photovoltaic converter configured to receive a light signal from a light source via a fiber optic cable and to output a supply voltage between about 3 volts DC and about 15 volts DC in response to the light signal; a DC to DC converter electrically coupled to the photovoltaic converter and configured to output a line level voltage between about 75 volts DC and about 140 volts DC in response to the supply voltage; and an electrical circuit electrically coupled to both the photovoltaic converter and the DC to DC converter, the electrical circuit being configured to receive the supply voltage and the line level voltage and to output a MEMS gate drive signal between about 60 volts DC and about 125 volts DC in response thereto.
