Summary:An energy efficient apparatus includes a switching device (12), a frequency dependent reactive device (14), and a control element (20) is provided. The switching device (12) is coupled to a source of electrical power (18) and includes a pair of transistors (40A,40B) and is adapted to receive a control signal and to produce an alternating current power signal. The frequency of the alternating current power signal is responsive to the control signal. The frequency dependent reactive device (14) is electrically coupled to the pair of transistors (40A,40B) for receiving the alternating current power signal and producing an output power signal. The frequency dependent reactive device (14) is chosen to achieve a desired voltage of the output power signal relative to the frequency of the alternating current power signal. The control element (20) senses an actual voltage of the direct current power signal and modifies the control signal delivered to achieve the desired voltage of the direct current power signal.
