摘要： An electric assembly includes a reverse conducting switching device and a rectifying device. The reverse conducting switching device includes transistor cells for desaturation configured to be, under reverse bias, turned on in a desaturation mode and to be turned off in a saturation mode. The rectifying device is electrically connected anti-parallel to the switching device. In a range of a diode forward current from half of a maximum rating diode current of the switching device to the maximum rating diode current, a diode I/V characteristic of the rectifying device shows a voltage drop across the rectifying device higher than a saturation I/V characteristic of the switching device with the transistor cells for desaturation turned off and lower than a desaturation I/V characteristic of the switching device with the transistor cells for desaturation turned on.

摘要： An IGBT/FET-based energy savings device, system and method wherein a predetermined amount of voltage below a nominal line voltage and/or below a nominal appliance voltage is saved, thereby conserving energy. Phase input connections are provided for inputting analog signals into the device and system. A magnetic flux concentrator senses the incoming analog signal and a volts zero crossing point detector determines the zero volts crossing point of the signal. The positive half cycle and negative half cycle of the signal are identified and routed to a digital signal processor for processing the signal. The signal is reduced by pulse width modulation and the reduced amount of energy is outputted, thereby yielding an energy savings for an end user.

摘要： A zero-crossing detection circuit can include: a state judging circuit that generates a judging signal based on whether a body diode of a synchronous power switch is conducting when the synchronous power switch is off; a regulation voltage generator that reduces a regulation voltage when the judging signal indicates that the body diode is conducting, and increases the regulation voltage when the judging signal indicates that the body diode is not conducting, where a detection voltage includes a sum of the regulation voltage and a voltage at a first terminal of the synchronous power switch; and a comparison circuit that compares the detection voltage against a voltage at a second terminal of the synchronous power switch, and generates a zero-crossing detection signal that is activated to turn off the synchronous power switch when the detection voltage equals the voltage at the second terminal of the synchronous power switch.
