Abstract
An apparatus comprising: a solid-state series switch positioned between a transmitter's high-voltage, direct current (DC) bus and a high-voltage DC power source, wherein the series switch is configured to establish an open circuit between the transmitter and the power source upon receiving a first trip signal; a solid-state shunt switch operatively coupled in shunt between the transmitter high voltage DC bus and a ground, wherein the shunt switch is configured to provide a short-circuit path from the transmitter to ground upon receiving a second trip signal; and a controller electrically coupled to the series and shunt switches, wherein the controller is configured to generate the first and second trip signals in the event that the controller receives a trouble signal from the transmitter, and wherein the first trip signal is sent to the series switch before the second trip signal is sent to the shunt switch.
