A power supply apparatus and a power supply method are described, wherein the non-polar characteristics of the electrodes of a capacitor is utilized to improve the energy utilization efficiency of a battery through reciprocating switches of polarity connection between the battery and the capacitor. The voltages of the capacitors can also stay at a near constant level using the polarity reversal mechanism.

An interface for providing thermal overload protection includes a switching device, a temperature indicating device, a drive circuit and a thermal monitoring circuit. The thermal monitoring circuit is coupled across the temperature indicating device and provides a shutdown signal to the drive circuit when the temperature of the switching device is above a predetermined temperature level as indicated by a temperature signal provided by the temperature indicating device. The drive circuit responds to the shutdown signal by removing current sources and current sinks from a control terminal of the switching device at which point leakage currents cause the switching device to reduce a drive current to an inductive load.

A system and method of managing the energy stored in a single ignition coil of a distributor inductive ignition for an engine. The engine comprises a plurality of cylinders and the ignition coil has a primary coil current. The ignition coil has a stored energy and a released energy during an ignition period. A pre-dwell time period and a pre-dwell current level is determined. The stored energy of the ignition coil and the released energy of the ignition coil are balanced during the ignition period at least in part by dwelling the primary coil current in the ignition coil at substantially the pre-dwell current level.

An ignition system providing power and duration controlled ignition spark, comprises a spark controller, first switching energy accumulator, storage capacitor, and second switching energy accumulator with an ignition coil. The ignition system utilizes dual means of switching energy accumulation, internal energy transfer, and three means of energy release to the ignition spark, working in all possible combinations managed by means of the spark controller depending on engine operating conditions, and provides continuous bipolar ignition spark. Spark profile is regulated by means of control signals (2) and (3) based on their frequency, duty cycle, interrelation, and running time.
