摘要： A circuit for extending the operating time of a battery is provided. A power source, typically a battery or other portable voltage source, is cyclically connected into a tuned circuit that includes a load. The circuit includes a means for switching the voltage source into and out of the circuit. The switching means also provides an alternate conduction path during the time the voltage source is not connected to the circuit so that current, and hence energy, can flow through the load. In this manner, the battery is actually in use for brief intervals of time while the load receives a constant energy supply from the circuit.

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.

The power stage includes a control FET transistor (Q1) having a first terminal, a second terminal, and a gate, the first terminal being connected to the input port. An energy storage element (Lo) has a first terminal connected to the control FET output terminal and a second terminal connected to the output port. A driven FET transistor (Q2) has a first terminal connected to ground, a second terminal connected to the first terminal of the energy storage element, and a gate. A driver circuit (81) has an input adapted to receive a control signal, and provides first driver signal to the control FET gate and a second driver output signal to the driven FET gate. The driver circuit has a power supply node for receiving power to power the driver circuit, which is connected to a power supply external to the converter circuit. A driver powering circuit is arranged to derive power from the first terminal of the energy storage element and provide it to the power supply node of the driver circuit after an initial period of operation of the converter circuit.

摘要： A method according to the invention includes the steps of inferring the peak current through the inductor (303) as a function of input voltage and inductor charge time, and deriving the current available to the load based upon the flyback voltage during discharge of the inductor (303). In terms of apparatus, in a switching power supply of the type wherein a switching device (302) is used to charge an inductor (303) that discharges to a load, the invention provides devices arranged for detecting output current without the need for a resistor or other component in series with the load. In the preferred embodiment, these devices include electrical components operative to generate a signal indicative of peak inductor current, and a switch (302) for switching the signal to provide a waveform, the integral of which is proportional to peak inductor current multiplied by the duty cycle of the discharge of the inductor (303).

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.

摘要： A power conversion system, preferably a buck converter (310, 320, 330), having an oscillator, a pulse width modulator, and a nonoverlap clock generator and level shifter, wherein the improvement comprises the elimination of an external resistor divider is described. The buck converter can convert input ranging from approximately 3 V to 5 V down to approximately 0.7-1. OV, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V without the use of resistor dividers. The voltage input identifiers select one of the possible output settings for flexibility and accuracy. The integrated field emitting transistors can provide a continuous current of at least 6 A. Additionally, peak current mode and an oscillator enable multiphase operation, up to ten buck converters, for up to 6OA output current. The multiphase operation reduces the output inductor size, and number of bulk capacitors. Moreover, the multiphase operation yields higher efficiency and provides high transient response for demanding applications.

摘要： A boost converter in which the conventional boost diode is replaced by a bidirectional normally conducting semiconductor switch. The circuit may be implemented so the bidirectional switch is self-driven by connecting a low voltage Schottky diode between a first gate-source terminal pair. An inrush current protection function may be provided by utilizing a second gate-source terminal pair to turn the switch on and off independent of the self-driven operation in response to predetermined excessive load current conditions. The inrush current protection function is implemented by use of a second Schottky diode connected between the second gate and source terminals, and an RC circuit connecting the second gate terminal to the return rail for the converter power output transistor with an externally controlled switch connected to the RC circuit to control the bias according to the load current.

摘要： Automatically changing the tap position in a load tap changer includes noting a polarity of a first tap position of a load tap changer. A duration for which one or more consecutive tap positions of the load tap changer collectively have had the noted polarity also is noted. The one or more consecutive tap positions include the first tap position. The duration for which the one or more consecutive tap positions collectively have had the noted polarity is compared to a threshold value. A change is made from the first tap position to a second tap position with a polarity that is different than the noted polarity when the duration for which the one or more consecutive tap positions collectively have had the noted polarity is longer than the threshold value. A change may be made from the second tap position back to the first tap position.
