<p>A bias circuit controlling the power transistor (Q2) in a transistor amplifier circuit for suspressing the arc formed across the bimetal contacts in a glow plug (18) controller for diesel engines. The bias circuit generates a load line for a transistor (Q2) which has a high voltage, low current portion and a high current, low voltage portion. The arc is formed when the bimetal contacts, which may be slow operating, is required to break a high current, high voltage line. </p> |
