    摘要: Switched power converter with hold-up time and harmonics reduction connected to an AC power mains through a first rectifier means (13) and connected to conversion means (19) supplying a regulated voltage. An energy storage means (16) connected in parallel with the rectifier means (13), absorbs or supplies current to the conversion means (19), by adapting the conducting periods of two switching devices in such a way that determines the voltage level on the storage means (16) and assures a sinusoidal current at input terminals (11, 12). The two switching devices are switched in a complementary manner by means of a first control means included in the energy storage means (16).

    摘要: A DC/DC conversion circuit of the type that implements the "forward PWM" topology includes a DC/AC converter, a self-driven synchronous rectifier which rectifies the alternating voltage signal coming from the DC/AC converter, and a filter that filters the rectified signal, thereby obtaining the DC output voltage from the DC/DC conversion circuit. This DC/DC conversion circuit is characterized in that the DC/AC converter includes means to generate an alternating signal with a square waveform that does not take zero instantaneous values such that no current flows through the body diode of either of the transistors of the self-driven synchronous rectifier.
