    Abstract: It is presented a switched-mode power converter comprising: a first switch configured to be used for effecting a desired output voltage or a desired output current on an output of the switched-mode power converter; and an over-voltage controller configured to detect an input voltage and to control the first switch. The over-voltage controller is configured to, as a result of detecting an over-voltage of the input voltage, decrease a resistance of the first switch such that any over-voltage on the output is attenuated. A corresponding method is also presented, as well as the switched mode power converter comprised in a mobile communication terminal and a charger for electronic apparatuses.

    Abstract: An over voltage protection device (210) for a GFCl (10) having a voltage divider network (211 & 212) connected across t line terminals (300 & 310) of the GFCI, and an over voltage detecting diode (214) connected between the voltage divider network and a gate terminal of an SCR (Q1). The voltage divider and diode cause a signal to be fed to the gate terminal the SCR to trip the GFCI when an over voltage condition exists at the line terminals. The voltage divider is adjustable, with the sensitivity of the over voltage protection varying in accordance with adjustment of the potential from the voltage divider. In an embodiment of the invention, the circuit includes an indicator (216), such as a photodiode, which indicates the occurrence of an over voltage condition. In addition, a blocking diode (217) is connected between the gate terminal of the SCR and a triggering terminal of an integrated circuit of the GFCI where the over voltage detecting diode conducts curerrent to the gate terminal when an over voltage condition occurs, and the blocking diode conducts current to the gate terminal the SCR when a ground-fault condition occurs.

    Abstract: Systems and methods presented herein provide for the control of electrical energy discharge from an electrode. In this regard, a sensor detects electrical energy discharged from the electrode and generates an electronic signal representative of a detected electrical energy discharge. Such a sensor may detect an electric field and/or light from the electrical energy discharge. The sensor may generate the electronic signal therefrom for subsequent processing. Accordingly, the system also includes a controller communicatively coupled to the sensor to determine a spurious discharge of the electrical energy discharge from the electrode. The controller processes the electronic signal to control at least one characteristic (e.g., voltage) of the electrical energy provided to the electrode. The controller may change a voltage of the electrical energy to the electrode in response to determining a spurious discharge of the electrical energy discharged from the electrode.

    Abstract: A circuit for protecting an electronic device including a differential nulling avalanche clamp circuit (200, 300) and method of using the circuit in an electronic system (100) to limit radio frequency overdrive. The electronic system (100) includes a surge clamp (130) coupled to dissipate an electrical surge effect of a first frequency from a noise sensitive node (140) and a ring wave clamp (120) coupled to dissipate an electrical surge effect of a second frequency from the noise sensitive node (140). The ring wave clamp circuit (200, 300) includes a first bipolar junction transistor (210, 310), a second bipolar junction transistor (220, 320) coupled to the first bipolar junction transistor (210, 310), and a resistive circuit (230, 330, 340) coupled to the first and second bipolar junction transistors (210, 220, 310, 320). A method of using the electronic system (100) in a device to limit radio frequency overdrive includes the steps of driving an output node with the radio frequency signal subject to overdrive effects (410), clamping a first order overdrive effect on a first node using a first clamp circuit (420), and clamping a second order overdrive effect on the first node using the differential nulling avalanche clamp circuit (430).
