Abstract: A power supply includes a power supply circuit and a power-on circuit controlling transitioning of the power supply circuit to a turned-on state. The power-on circuit includes a code driver, a controller coupled to the power supply circuit and code driver, and a transducer to detect a wireless control signal and generate an enable signal based thereupon. A transistor has a first conduction terminal coupled to the code driver, a second conduction terminal coupled to the controller, and a control terminal coupled to the transducer to receive the enable signal so the transistor switches based thereupon. The code driver detects a code embedded in the wireless control signal based upon switching of the transistor, and generates a power on signal for the controller based upon the code. The controller causes the power supply circuit to transition from the turned-off state to the turned-on state based upon the power on signal.

Abstract: A rectifier bridge circuit includes a first SCR/IGBT switch and a second SCR/IGBT switch coupled to a circuit input to receive an ac input voltage. The first and second SCR/IGBT switches are alternatively switchable to generate a rectified voltage at a circuit output. Control currents coupled to control terminals of the first and second SCR/IGBT switches are power supply sourced from an auxiliary dc source generated by rectifying the ac input voltage. The control currents are generated by current sources coupled between the auxiliary dc source and the control terminals of the first and second SCR/IGBT switches. The current sources are selectively activatable to produce gating currents for switching on and off the first and second SCR/IGBT switches. A controller unit is provided to control the current sources via level shifter circuits. The control implements progressive conduction time of the first and second SCR/IGBT switches so as to provide inrush current limitation.

Abstract: A power supply apparatus includes a power supply circuit and a power-on circuit. The power-on circuit detects a remotely transmitted control signal and causes a transition of the power supply circuit to a turned on state. The power-on circuit includes a transducer configured to provide a power-on signal in response to the remote control signal. The transducer triggers transition to the turned on state through a switch driven by the power-on signal output from the transducer and arranged to supply a power supply circuit enable signal. A DC blocking capacitor is connected between an output of the transducer and a control terminal of the switch.
