摘要： In at least one embodiment, the invention provides a bidirectional amplifier and method of control that enables immediate feedback directly from the output for fast response and low distortion. Mechanisms responsive to instantaneous feedback eliminate undershoot, overshoot, and sub-harmonic behavior. One embodiment comprises two switches and a single two-terminal inductor. Another embodiment produces a bipolar output from a single unregulated supply rail. The use of Predictive Energy Balancing controls yield high efficiency and low total harmonic distortion. These amplifiers are suited for audio application, and can drive piezo or dynamic speakers.

摘要： In certain embodiments, driver circuitry generates drive signals to drive driven circuitry to transition between first and second states. The driver circuitry has a first-to-second driver circuit that generates a first drive signal to drive the driven circuitry to transition from the first state to the second state and a second-to-first driver circuit that generates a second drive signal to drive the driven circuitry to transition from the second state to the first state. The driver circuitry includes two complementary triggered current pulse generators (described in U.S. Pat. No. 10,554,206) that combine to efficiently provide switch drive for a FET or other reactive load. The triggered drive has fast edges for low switching losses. In certain embodiments, the low power triggered drive circuitry can respond to a slowly changing feedback signal to switch a FET so as to regulate a power converter output.

摘要： The disclosure provides a power converter and method for controlling same, comprising a plurality of switch elements, an inductive reactor, and at least two ports for the movement of electrical energy. Any energy-moving port may be made unipolar, bidirectional, bipolar, or bidirectionally bipolar. Ports may be equipped with sensing circuitry to allow the converter output to be controlled responsively to an input signal. The disclosure may be configured to be used in many ways, for example, as a power-supply, as an amplifier, or as a frequency converter. The disclosure may comprise energy predictive calculating means to obtain excellent transient response to line and load variations. The disclosure may also include a switch to create a low impedance path around the inductor to allow current to recirculate through the inductor when it is not needed at any of the ports.

摘要： In certain embodiments, a power converter has an input side connected to receive AC input power at an input node and an output side connected to produce a regulated output power at an output node. The power converter has a transformer having at least one primary winding on the input side and at least one secondary winding on the output side. The power converter has at least one multi-functional inductor that supports both main regulation and supplemental regulation in a time-multiplexed manner such that, during main regulation, input energy is transferred from the input node to the output node via the multi-functional inductor, and, during supplemental regulation, the stored energy is transferred from the at least one energy storage element to the output node via the multi-functional inductor. Depending on the embodiment, the multi-functional inductor(s) may be one or two secondary transformer windings or a separate buck inductor.

摘要： In certain embodiments, the present invention provides a compound power converter in which the majority of power passes from input to output through only a single stage of power conversion. At least one embodiment includes a main converter with an auxiliary output.

IPC分类号： H03K19/003 , H03K17/30
摘要： An n-type transistor and a p-type transistor are connected in series such that, when the two transistors are turned on, current flows from the collector of the n-type transistor to the collector of the p-type transistor. A positive-feedback capacitor is connected between the collector of one transistor and the base of the other transistor. The two transistors turn on together when the base voltage of the n-type transistor exceeds the base voltage of the p-type transistor by at least the sum of the turn-on threshold voltages of the two transistors and (i) the two transistors turn off together when the base voltage of the n-type transistor fails to exceed the base voltage of the p-type transistor by at least that sum. The positive-feedback capacitor ensures that the two transistors turn fully on and off together. In certain embodiments, the circuitry can be controlled to operate as a current pulse generator.
