Abstract
An electromagnetic fuel pump embodying a blocking oscillator relatively insensitive to breakdown under overvoltage conditions is disclosed. The blocking oscillator embodies an overvoltage protection circuit which renders the amplifier in the blocking oscillator portion of the circuit nonconductive during any overvoltage conditions. As a result, the Darlington amplifier only has to withstand the overvoltage and the probability of current mode failure is significantly reduced. A filter circuit surpresses the generated RFI to levels below industrial and military standards.
