Patent ID: 8708438

Claim:
A printer comprising: an energy storage device; a single stage power factor correction charger for charging the energy storage device and for providing a first DC voltage; a first DC-to-DC voltage converter for converting the first DC voltage to a second DC voltage; first printer electronics powered by the second DC voltage; a second DC-to-DC voltage converter for converting the first DC voltage to a third DC voltage, second printer electronics powered by the third DC voltage; and a mix signal application specific integrated circuit to provide a first pulse width modulated signal to the first DC-to-DC voltage converter to control the first DC-to-DC voltage converter based on a first feedback signal from the first DC-to-DC voltage converter and to provide a second pulse width modulated signal to the second DC-to-DC voltage converter to control the second DC-to-DC voltage converter based on a second feedback signal from the second DC-to-DC voltage converter, wherein the first voltage is less than the second voltage, wherein the first voltage is greater than the third voltage, and wherein the energy storage device provides power for a peak load condition of the first printer electronics, wherein the charger comprises: a full wave rectifier for receiving an AC voltage to provide a rectified signal; a capacitor coupled to the full wave rectifier to remove noise from the rectified signal; a pulse width modulation controller and power factor correction circuit coupled to the full wave rectifier and the capacitor; and a flyback converter coupled to the pulse width modulation controller and power factor correction circuit to provide the first DC voltage.
