    摘要： An oscillator is coupled to a first side of a galvanic barrier for supplying thereto an electric supply signal. The oscillator is configured to be alternatively turned on and off as a function of a PWM drive signal applied thereto. A receiver circuit coupled to the galvanic barrier receives therefrom a PWM power control signal. A signal reconstruction circuit coupled between the receiver circuit block and the oscillator provides to the oscillator a PWM drive signal reconstructed from the PWM power control signal. The signal reconstruction circuit includes a PLL circuit coupled to the receiver circuit block and configured to lock to the PWM control signal from the receiver circuit block. A PLL loop within the PLL circuit is sensitive to the PWM drive signal applied to the oscillator. The PLL loop is configured to be opened as a result of the power supply oscillator being turned off.

    摘要： A controller (3) includes an AC voltage generator (12) that generates first to Nth AC voltages, a DC voltage generator (13) that converts the first to Nth AC voltages into first to Nth DC voltages, respectively, and a driver (14) that turns on and off a switch (1) based on the first to Nth DC voltages. The AC voltage generator (12) includes first to Nth isolation transformers (T1 to TN). The primary windings of the nth and (n+1)th isolation transformers receive an AC source voltage. The nth to first isolation transformers are sequentially connected. The (n+1)th to Nth isolation transformers are sequentially connected. The first to Nth isolation transformers respectively output the first to Nth AC voltages from their respective secondary windings.

    摘要： The present invention relates to a high voltage switch circuit, comprising an input port adapted to receive a pulse type input current and an output port, which can be used selectively to conduct an output current to a corresponding electrical load. The switch circuit comprises a buffer stage adapted to sense the input voltage at said input port and to provide a buffered voltage that follows said input voltage. The switch circuit comprises complementary switches electrically connected between said input port and said output port and a voltage level translator electrically connected with said switches, said buffer stage and a control terminal that provides a control signal. The voltage level translator provides suitable gate voltages at the gate terminals of said switches, so that the operation of these latter can be controlled by said control signal.

    摘要： The application of a controlled amount of alternating current (AC) power to an electrical load is achieved in a power switching circuit utilizing phase-control. In the switching circuit, a first analog signal is generated and repeats in every half-cycle of the AC power voltage waveform. A second analog signal is generated and is changeable in value either in a predetermined manner, or in response to the control input signal. The second signal is not synchronized with the half-cycles of the power source. A comparator detects when the first signal intersects the second signal in value and thereupon initiates gating of a switching device, such as a silicon-controlled rectifier.
