Abstract

PURPOSE: To transfer energy quickly by providing a storage coil and a capacitor connected with an electronic switch means, and forming a resonance circuit by connecting the storage coil with a power supply and then connecting the coil with the capacitor. CONSTITUTION: The guide circuit for a plurality of inductive loads Li has an input terminal 1 to be connected with a battery wherein the load Li comprises a solenoid for operating the electric injector of a diesel engine for automobile. A storage coil L1 is connected with the input terminal 1 through a control electronic switch SW1 which is in pause time. Similarly, other control switch SW2 is connected between the storage coil L1 and the ground. Furthermore, a plurality of branch circuits are connected in parallel with a capacitor C. An electronic controller ECU comprises a microprocessor and an I/O interface circuit and controls respective switches SW1 , SW2 and SW3 . The storage coil L1 is connected with the capacitor C to form a resonance circuit for discharging the load Li .
