    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: Universal switched power converter connected to a voltage source and, based on the level of the voltage received, this is applied to a first primary circuit comprising a first switching device (14-1) or to a second primary circuit comprising a second switching device (15-1). Control means (PWM) adapt the conducting period of the switching device connected to input terminals for regulating an output voltage and adapt the conducting period of the switching device not connected to the input terminals for demagnetising the core of a transformer (T) during the non-conducting period of the switching device connected to the input terminals.

    摘要: A converter device that transforms an input voltage (VE) into several output voltages (V1, . . . ,VN) includes a transformer (T), a first switching control device (PWM) that generates a first switching control signal (Q1) to control the switching of a first switching element (M1) and thereby regulate a main output of the converter, and a second switching control device (SDCC) that generates a second switching control signal (Q2) which is a function of both the first switching control signal (Q1) and of a second output voltage (V2). This second switching control signal (Q2) controls the switching of a second switching device (SDC) in order to regulate a second output voltage of the converter device.
