  • Publication number: 20200389083
    Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for discharging an output capacitor of a power supply is disclosed. The power supply includes a primary side for receiving a signal to be converted and a secondary side for outputting a converted signal. The method involves detecting whether synchronous rectification (SR) circuitry at the secondary side is inactive, determining that the primary side is disconnected from a mains voltage when the SR circuitry is detected to be inactive, and discharging an output capacitor at the secondary side based on the determination that the primary side is disconnected from the mains voltage.

  • Publication number: 20170063307
    Abstract: Embodiments of a driver circuit for a power stage of a class-D amplifier and a class-D amplifier are described. In one embodiment, a driver circuit for a power stage of a class-D amplifier includes serially connected transistor devices connected to a gate terminal of a power transistor of the power stage of the class-D amplifier, a voltage generator connected between a gate terminal of a first transistor device of the serially connected transistor devices and a source terminal of the power transistor, and a current multiplier connected between the gate terminal of the power transistor and one of a source terminal and a drain terminal of the first transistor device. The current multiplier is configured to produce an output current that is proportional to a current at the one of the source terminal and the drain terminal of the first transistor device.

  • Patent number: 8390208
    Abstract: A drive circuit for delivering an AC voltage to an array of electro-luminescent lamps (8a to 8n) includes a single coil (1), the energy in which is transferred to each lamp through a corresponding switch assembly (10a to 10n) having positive and negative-going paths for conducting positive and negative voltages to the corresponding lamp. The magnitudes of the voltages applied to the parallel-connected lamps are controllable so that the illumination levels of the lamps are individually adjustable.
