摘要： A matrix converter system and control method includes a matrix converter, a generator, a plurality of output capacitors, and a controller. The matrix converter includes a plurality of switches and is connected between a multiphase input and a multiphase output. The plurality of output capacitors are connected between the multiphase output and ground. The generator is connected to the multiphase input and includes internal inductances. The controller is configured to control the plurality of switches to control active current and reactive current from the generator based on the internal inductances of the generator. The active and reactive currents are controlled to charge the plurality of output capacitors. The matrix converter operates in a current control mode and is able to boost output voltage above the input voltage level.

摘要： A load control device may control the amount of power provided to an electrical load utilizing a phase control signal that operates in a reverse phase control mode, a center phase control mode, and a forward phase control mode. A load control device may be configured to determine that the electrical load should be operated via a phase control signal operating in a forward phase-control mode. After determining to operate the electrical load via the phase control signal in the forward phase-control mode, the load control device may provide the phase control signal in a reverse phase-control mode for a predetermined period of time to the electrical load, for example, to charge a bus capacitor of the electrical load. Subsequently, the load control device may be configured to switch the phase control signal to the forward phase-control mode and provide the phase control signal in the forward phase-control mode to the electrical load.

摘要： A solution that intends to solve the problem of providing a single-stage bidirectional power conversion system (PCS) with a controllable power factor and the capability to regulate the current in the DC side. Disclosed is a single-stage, bidirectional and high-frequency isolated PCS, including a high-frequency transformer (HFT), a three-phase-to-single-phase matrix converter (MC), a full-bridge (FB) AC to DC converter, and a control system, where the control system outputs are connected to the switches of the MC and the FB converter. Moreover, the PCS output can also form a DC network for energy supply of several devices. This system converts three-phase AC power input from the network into DC power output that can be used for example to charge an energy storage device or supply a direct current distribution system. It is also possible to convert DC power input into AC power output to supply the network.

摘要： A converter includes: a terminal that receives code-modulated power into which first alternating-current power has been code-modulated with a modulation code; and a circuit that converts the code-modulated power with a conversion code to generate second alternating-current power. The conversion code is based on the modulation code. A frequency of the second alternating-current power is lower than a frequency of the first alternating-current power.

摘要： Methods and systems for smart transfer switch circuits and operation, and for operation of transfer and/or cutoff switches in combination with a power-packet-switching-architecture (PPSA) power converter. The transistors of the transfer and cutoff switches, and the transistors of the phase legs of the PPSA power converter if present, preferably all use double-base bipolar transistors which have low on-state series resistance as the switching elements.
