SQUARE WAVE TRANSISTOR RELAXATION OSCILLATOR

摘要

A control system, particularly for a diesel engine, has a square wave oscillator, the output from which is fed to the primary winding of a transformer having a secondary winding, the coupling between the windings being varied to vary the output of the secondary winding. This signal can provide an input to a control circuit for determining the fuel supply to the engine, or can be used for other purposes.
