Abstract
A fast insulated gate bipolar transistor (IGBT) driver circuit for trunking waveforms in external defibrillators is provided. An input circuit is provided to receive input signals. An isolation transformer is provided to isolate the output from the input. A biasing circuit is connected to the isolation transformer for biasing the IGBT. In response to the biasing circuitry, the IGBT rapidly switches between operational states to truncate waveforms at any point during the delivery of energy to a patient.
