Claim:
1. A switch controller comprising: a primary side comprising signal transmission circuitry to transmit signals representative of a desired transition of a switch between an on state and an off state or between an off state and an on state, the signals having a signal duration; a secondary side isolated from the primary side and comprising a signal transformer galvanically isolating the primary side from the secondary side but inductively coupling the signal transmission circuitry to the signal reception circuitry, the signal transformer having a primary side winding coupled to the signal transmission circuitry and a secondary side winding coupled to the signal reception circuitry; and a switch coupled to switch a relatively low impedance onto the primary side winding during pauses between transmissions of the signals representative of the desired transition of the switch, wherein the secondary side signal reception circuitry further comprises a validation circuit to validate signals received by the signal reception circuitry, the validation circuit comprising:
