Electrical disturbance reducing circuit for DC motor, has auxiliary voltage source making series transistor fully conductive, and analyzer circuit analyzing supply voltage to increase resistance of transistor
The circuit has a series transistor arranged in a supply lead from a DC voltage source to a DC motor. An auxiliary voltage source (50) makes the series transistor fully conductive when supply voltage furnished by the voltage source is free of electrical interference. An analyzer circuit analyzes the supply voltage to increase resistance of the transistor upon occurrence of electrical interference in the supply voltage.
