Solid state power controller

A solid state power controller configured to supply electric power from an AC power supply to at least one load via at least one power distribution channel, the at least one power distribution channel comprising a primary solid state switching device and a secondary solid state solid state switching device connected in series;

• each of the primary and secondary solid state switching devices having a first terminal (D), a second terminal (S), and a control terminal (G), each of the primary and secondary solid state switching devices configured to switch between an OFF operation mode in which the second terminal (S) is electrically disconnected from the first terminal, and an ON operation mode in which the second terminal (S) is electrically connected to the first terminal (D), according to a control voltage applied to the control terminal (G);
• wherein the solid state power controller comprises:
• a primary control terminal driver configured to supply a primary control voltage to the control terminal (G) of the primary solid state switching device with respect to a reference potential (R);
• and
• a secondary control terminal driver configured to supply a secondary control voltage to the control terminal (G) of the secondary solid state switching device;
• wherein the secondary control terminal driver is electrically isolated from the primary control terminal driver;
• and
• wherein the secondary control terminal driver is configured to supply the secondary control voltage to the control terminal (G) of the secondary solid state switching device based on a control signal provided by the primary control terminal driver.
