Abstract
A power supply system includes a switching type regulated power supply operable to provide switched regulated D.C. output voltages. A first winding having a first terminal and a second terminal is provided. The first terminal is connected to be energized by the switched D.C. output voltage of the switching type regulated power supply such that a switched D.C. voltage is developed at the second terminal of the first winding. A second winding electromagnetically coupled to said first winding and having a first and a second terminal is also provided. A capacitor and a diode are coupled between the first and the second terminal of the first winding. Means connect the diode and the capacitor to the first terminal of the second winding. The power supply system may be part of a postage meter system. A postage meter includes accounting means operatively coupled to a postage printing means. The accounting means accounts for postage printed by the printing means. The accounting means include a nonvolatile memory for storing accounting and other data when no power is being supplied to the meter.
