摘要： In one embodiment, a level-shifter for driving a high-side power switch with sub-nanosecond timing integrity, without requiring a high-side gate-drive power supply, is provided. A drive source is connected to the gate of a power switch through a common-mode choke, and the latter level-shifts the common-mode voltage of the drive signal to the common-mode level of the power switch. The same level-shifter may also be used to drive a low-side power switch to avoid ground bounce.

摘要： A power-conversion regulator comprising an inductive reactor, an output filter reactor, and a switch for admitting energy to the inductive reactor, additionally comprises computation circuitry responsive to the flux in the inductive reactor, to a reference signal, to an output voltage, and sometimes to an output load current, for computing the quantity of energy that must be supplied to a load and to the output filter reactor to regulate the output voltage or current to a desired relationship with the reference signal during each chopping waveform cycle driving the switch. As the inductive reactor is charged from an input energy source, the computation circuitry predicts whether the energy in the inductive reactor has become adequate for the regulation.

摘要： The present invention provides a voltage regulator/power converter capable of bidirectional power propagation, fitted with controls capable of raising and lowering voltages with unprecedented speed and accuracy. The bidirectional capability allows energy stored in capacitors to be returned to system power sources. In one embodiment of the invention power is supplied from a power source (on a first port of the power converter) to the load (on a second port of the power converter) through the converter and then, when load voltage is reduced or turned off, energy in the load capacitance is returned from to the power source. In an alternative embodiment energy from load capacitance is stored or used by a device on a third port of the power converter.
