Capacitor heat reduction apparatus and method
View Patent ↗High capacitance capacitors are provided to supply or accept large currents. As current flow through a capacitor increases, heat may be generated. Above a certain threshold temperature or current, a capacitor may fail. The present invention addresses capacitor's tendency to fail at higher currents and/or higher temperatures.
