Abstract

See full text

A controller protection circuit for a voltage power optimizer. The circuit having: a first terminal for connecting to a first end of a winding in the voltage power optimizer; a second terminal for connecting to a second end of the winding in the voltage power optimizer; and a thyristor. The controller protection circuit also includes a thyristor gate control circuit. The thyristor gate control circuit is configured to: set the gate control signal such that the thyristor is configured to conduct in response to a potential difference between the anode terminal and the cathode terminal of the thyristor; and set the gate control signal such that the thyristor is configured not to conduct in response to a signal received from a voltage controller. The thyristor gate control circuit includes a normally-on switch having a conduction channel and a control terminal; and a photovoltaic isolator configured to set the gate control signal such that the thyristor is configured not to conduct in response to a signal received from a voltage controller.
