AC to DC power supply with supplemental energy storage
 An AC to DC power supply is disclosed which converts an AC input voltage to a DC output voltage and supplies the DC output voltage to power devices. The power supply includes a transformer for reducing a voltage level of the AC input voltage and an energy storage device in the form of a Bolder battery that has low internal resistance and is capable of generating high power generally instantaneously. The energy storage device enables the power supply to meet high electrical loads that exceed the output of the transformer.
