Integral power supply and capacitor

摘要

Capacitance C is structurally combined with a battery B eg. Ni - Cd and electrically coupled to the battery such that the capacitance substantially compensates for voltage variations at the terminals of the battery caused by the internal impedance of the battery at pulsed loads. The capacitance may be wound on or in a dielectric sheath D of the battery or the capacitance and the battery may be formed of strips which are superimposed and spirally wound together. Enables optimisation of the capacitance for the type of power supply and since the capacitance is not positioned in the circuitry reduction in size and weight of the electronic apparatus.
