摘要

A circuit for generating a saw-tooth current waveform in a coil comprises a parallel resonant circuit, of which the coil in which the saw-tooth current is to be generated forms part. The parallel resonant circuit includes two capacitors in parallel and a first diode, in parallel with one of the capacitors, and in parallel with which is a switching transistor connected via a second diode to the cathode of the first diode. Input energy from a power source is fed to the junction between the second diode and the switching transistor via an inductance which forms a resonant circuit with a further capacitor forming at least part of a reactance in parallel with the second diode.
