Method and device for controlling inductive loads
Abstract:
Control circuitry for inductive loads comprehending a DC power source (DC), electrical switches (A and R) and appropriate electrical conductors to direct current to an inductive load, as the control system includes a primary circuit and a secondary circuit which is partly concurrent with the primary electrical circuit. The primary electrical circuit includes a series of DC power sources (DC), an inductive load in the form of an electric motor (M) or transformer (T) and a capacitor (C), while the secondary electrical circuit includes the inductive loads and capacitor (C), since the two electrical switches (A and R) are so arranged that the power of a first operational phase is driven through the primary electric circuit by the voltage supplied by the DC power source (DC) while the current in another phase of operation runs through the secondary electric circuit by the voltage supplied by the capacitor (C).
