摘要： A power factor corrector raises power factor at low loads or high mains voltages by modifying the switch timing or the current received by the power converter. It achieves this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time, to thereby control the current received by the converter to compensate for current received by the intermediate filter. Some embodiments may employ a feedback system to produce one or more error signals that modify the control signal used to control the operation of the converter. Various embodiments may also include additional stages that limit the compensation range of the error signal.

摘要： An electrical circuit for emulating a capacitance, comprises a physical capacitor which is charged by charge flow from the input of the electrical circuit. An amplifier amplifies the voltage at the input of the electrical circuit such that the physical capacitor is charged with a larger change in voltage than the change in voltage at the input. This implements an effective multiplication of capacitance. A reset system resets the physical capacitor without drawing charge from the input of the electrical circuit. This extends the voltages which can be provided to the input.

摘要： A switched mode power supply (SMPS) is disclosed. The SMPS includes a mechanism for discharging charge stored in an input capacitor, upon the SMPS becoming disconnection from the mains, for instance by being unplugged. The SMPS includes a detector for detecting the disconnection of the mains, and a discharge circuit. The discharge circuit comprises a discharge element. The discharge element may be a part of the SMPS which is used otherwise, for instance, a high-voltage current source, or a bus capacitor or it may be an additional element, for instance a resistance load. The discharge circuit is adapted for, in response to the detector detecting a disconnection of the mains, discharging the input capacitor along a path. The detector controls a switch which engages the discharge circuit upon the detection. The switch forms a part of the discharge path.Also disclosed are methods of operating an SMPS including a safety arrangement, and a controller adapted or configured to operate such methods.

摘要： Consistent with an example embodiment, there is a method of controlling a synchronous rectifier having an input signal having oscillations therein and a switch which is switchable between an open state and a closed state. The method comprises filtering the input signal to produce a filtered signal, comparing the filtered signal with a reference value, and opening the switch in response to the comparison, in which the filtering is active filtering.The active filtering may be based on determination of the peaks (positive and/or negative) of the signal, either directly, including a quarter period offset, or including decay—or a combination of the above; alternatively, the active filtering may be based on the a smoothing functions such as a switched low-pass filter or a short time integrator.
