Ignition device with low source voltage compensating circuit
Abstract
Abstract A CAPACITOR DISCHARGE TYPE IGNITION DEVICE, WHEREIN AN INTERMEDIATE TAP IS PROVIDED ON A PRIMARY WINDING OF AN OSCILLATOR TRANSFORMER INCORPORATED IN A DC-DC CONVERTER ADAPTED FOR BOOSTING THE VOLTAGE OF A STORAGE BATTERY, SAID INTERMEDIATE TAP AND THAT ONE OF THE TERMINALS OF SAID PRIMARY WINDING WHICH IS ON THE POWER SOURCE SIDE ARE CONNECTED WITH THE STORAGE BATTERY THROUGH A SWITCHING MEANS WHICH ARE UNDER THE CONTROL OF A VOLTAGE CONTROL ELEMENT ADAPTED TO DETECT THE TERMINAL VOLTAGE OF SAID STORAGE BATTERY, AND WHEN THE VOLTAGE OF THE STORAGE BATTERY IS LOWER THAN A PREDETERMINED VALUE, THE BATTERY IS SWITCHED TO SAID INTERMEDIATE TAP THEREBY TO PREVENT THE DROP OF THE OUTPUT VOLTAGE FROM SAID TRANSFORMER, WHILE A REVERSE CURRENT FROM SAID PRIMARY WINDING TO THE STORAGE BATTERY BEING STOPPED BY A DIODE.
