Abstract:
1. A method of alternator overvoltage protection comprising: providing a TRIAC and an alternator rotated by an engine having a magneto, wherein said alternator outputs a voltage when rotated by said engine; configuring said TRIAC to ground said magneto when said alternator operates in an overvoltage condition, thereby disabling said magneto, stopping the rotation of said engine, and stopping said alternator from outputting voltage; providing a transistor and a MOSFET; configuring said transistor to conduct when said alternator operates in said overvoltage condition; configuring said MOSFET to conduct when a voltage is imposed on a gate of said MOSFET by said conducting transistor; and configuring said MOSFET to direct a portion of current from said magneto to trigger a gate of said TRIAC when said MOSFET is conducting, thereby causing said TRIAC to conduct.
