ABSTRACT:
A hybrid blocking oscillator for an electromagnetic fuel pump is disclosed herein. The blocking oscillator embodies a temperature regulated bias control and two current dissipators for controlled dissipation of the currents induced in the solenoid and detection coils when the oscillator is in a blocked state. The disclosed hybrid circuit is capable of 5,000 hours of operation with a 99 percent reliability.
