1. A voltage supply circuit, comprising:

  • first storage capacitor chargeable by a high frequency AC voltage;

    control circuit connected to said first storage capacitor, said control circuit comprising switching controller means (42, 44, 40, 50,

         62) for transforming the voltage of said first storage capacitor (14) into a voltage on a second storage capacitor (40) by switching said switching controller means, a linear voltage regulator (100, 112,

         106) connected to said second storage capacitor (40) for providing an output voltage at an output terminal (102), and static starter circuit means (82, 84, 30, 22, 86, 20, 26, 64, 90,

         80) for inhibiting said switching of said switching controller means until a predetermined voltage has built up on said first and second storage capacitors (14,

         40).
