摘要： A POWER SUPPLY (300) INCLUDES A SUPPLY INDUCTOR AND A FIRST CAPACITOR COUPLED TO FORM A RESONANT CIRCUIT (305) TO GENERATE A RESONANT WAVEFORM IN A RESONANT OPERATION, DURING A FIRST PORTION OF AN OPERATION CYCLE OF THE POWER SUPPLY. A CHARGE STORAGE ELEMENT DEVELOPS AN OUTPUT VOLTAGE TO ENERGIZE A LOAD. A RECTIFIER IS COUPLED TO THE CHARGE STORAGE ELEMENT AND TO THE RESONANT CIRCUIT AND IS RESPONSIVE TO THE RESONANT WAVEFORM FOR APPLYING THE OUTPUT VOLTAGE BACK TO THE RESONANT CIRCUIT TO INTERRUPT THE RESONANT OPERATION, AT AN END TIME OF THE OPERATION CYCLE FIRST PORTION, WHEN THE RESONANT WAVEFORM PRODUCES A FIRST CHANGE OF STATE IN THE RECTIFIER. A FIRST SENSOR SENSES WHEN THE FIRST CHANGE OF STATE IN THE RECTIFIER OCCURS. A SOURCE OF A SUPPLY CURRENT IS COUPLED TO THE RECTIFIER AND RECTIFIED IN THE RECTIFIER TO PRODUCE A RECTIFIED CURRENT THAT IS COUPLED TO THE CHARGE STORAGE ELEMENT TO REPLENISH A CHARGE THEREIN, DURING A SECOND PORTION OF THE OPERATION CYCLE. A SWITCHING TRANSISTOR IS RESPONSIVE TO AN OUTPUT SIGNAL OF THE FIRST SENSOR FOR ENABLING THE SUPPLY CURRENT TO BE COUPLED TO THE RECTIFIER, DURING THE OPERATION CYCLE SECOND PORTION, AND FOR DISABLING THE SUPPLY CURRENT FROM BEING COUPLED TO THE RECTIFIER, DURING THE OPERATION CYCLE FIRST PORTION.(FIG 1)

摘要： The life of load tap changer contacts is monitored by detecting an arcing event; identifying arcing surfaces involved in the arcing event; calculating a per-unit loss of life for the identified arcing surfaces as a result of the arcing event; updating estimates of cumulative erosion for the arcing surfaces; comparing the updated estimates of cumulative erosion to a first threshold value; and signaling for action when at least one of the updated estimates of cumulative erosion exceeds the first threshold value.

摘要： A multi-phase synchronous buck converter having plural single phase synchronous buck converter stages, connected together to provide an output current to a load. A sensing circuit in each converter stage includes a variable gain current sense amplifier that determines the current through the shunt MOSFET to generate an output signal representative of the output current provided by that converter stage. The gains of the current sense amplifiers in each converter stage are preset such that the output signals from all the amplifiers are substantially equal, thereby balancing the power loss in all the converter stages by adjustment of the output currents using varying current sense gains to compensate for variations in the R DS-ON of the shunt MOSFETS.

摘要： A method and apparatus for converting a DC voltage to a lower DC voltage, provides for conducting current from an input terminal, through an inductor to charge a capacitor connected to the inductor at an output terminal and to provide a varying range of load current from the output terminal, alternately switching the input terminal between a supply voltage and a ground potential to produce a desired voltage at the output terminal that is lower than the supply voltage, while providing the varying range of load current, and disconnecting the input terminal from both the supply voltage and the ground potential to reduce an increase in voltage at the output terminal caused by a substantial reduction in the load current, while current through the inductor adjusts in response to the reduced load current.

摘要： A pre-bias protection circuit for a converter circuit including a switching stage having high- and low-side switches connected in series at a switching node and an output stage connected to the switching node having a capacitor having a pre-existing pre-bias voltage at startup of the converter circuit, the pre-bias protection circuit controlling discharge of the pre-bias voltage when the low-side switch is turned ON during a start up of the converter circuit. The pre-bias protection circuit includes a first circuit for providing a first output; a second circuit providing a second output; and a comparator circuit for comparing the first output and the second output and producing a third output comprising a pulse width modulated signal for driving the low side switch such that the pulse width modulated signal starts with a small duty cycle and thereafter increases to a larger duty cycle, thereby to prevent the pre-bias voltage from discharging during startup.
