摘要： A semiconductor chip includes a hardware performance monitor (HPM) unit and an HPM controller. The HPM unit is driven during an initial operation period, a first operation period, and a second operation period, outputs initial HPM data, first HPM data, and second HPM data in the initial operation period, the first operation period, and the second operation period, respectively. The HPM controller performs a first compensation operation of compensating a driving voltage of the semiconductor chip using the initial HPM data and the first HPM data, and a second compensation operation of compensating the driving voltage using the initial HPM data and the second HPM data. The HPM unit provides the initial HPM data, the first HPM data, and the second HPM data, which are correlated with performance of the semiconductor chip, to the HPM controller in a first mode, and does not provide this data in a second mode.

摘要： A method of switching taps of an on-load tap changer includes providing a main finger, a first side finger including a first solid state switch and a second side finger including a second solid state switch. The main finger, the first side finger and the second side finger are utilized to provide a connection between the taps and a power terminal of the on-load tap changer. The method also includes triggering the on-load tap changer to shift the fingers from a first tap to a second tap of the on-load tap changer when a tap change signal is received and utilizing the first solid state switch and the second solid state switch to commutate a current during the tap change operation.

摘要： A regulator to provide an output voltage of a constant level at an output node. In an embodiment, the regulator contains a pass transistor to provide a conductive path between a pair of terminals, with the resistance offered by the path being determined by a control voltage on a third terminal of the pass transistor and the conductive path coupling a first reference potential (e.g., power supply) to the output node. An amplifier generates the control voltage based on a difference of a reference voltage and a voltage proportionate to the output voltage. A control unit turns on a current source when the voltage at the output node is below the desired constant level and turns on a current sink when voltage at said output node is above the constant level, to quickly correct for any variations in the output voltage due to load changes.

摘要： An input waveform follow-up AC power source system is shown, which can obtain a desired sinusoidal voltage or current wave continuously and with the same or a similar waveform from a constant power source, as well as being small in size and light in weight.The AC power source system, which provides a desired AC voltage or current from an AC power source, comprises a first AC switch provided between the input side and the output side and on-off operated in a predetermined cycle, and a second AC switch provided on the output side of the first AC switch and at a position to short-circuit the output side and on-off operated conversely to the first AC switch. A predetermined pause time is provided between the operations of the first and second AC switches. Each AC switch has two semiconductor elements, and diodes each connected between controlled terminals of and in opposite conduction polarity to each semiconductor element, like polarity controlled terminals of the two semiconductor elements being connected to each other, the same control signal being supplied to a control input terminal of each semiconductor element for on-off switching AC between the other controlled terminals of the semiconductor elements.
