摘要： A method of decoupled modulation of a direct AC/AC MMC between a first AC network having a first waveform and a second AC network having a second waveform, the MMC having a double-star topology with a plurality of phase legs, each phase leg having a first branch and a second branch, each of the first and second branches comprising a plurality of series connected bipolar cells. The method includes performing a first modulation based on a reference signal of the first AC network, independently of a reference signal of the second AC network, to generate, for each phase leg, a first integer command signal corresponding to a first combination of cell states in the first and second branches of the phase leg needed for generating the first waveform. The method also comprises performing a second modulation based on the reference signal of the second AC network, independently of the reference signal of the first AC network to generate, for each phase leg, a second integer command signal corresponding to a second combination of cell states in the first and second branches of the phase leg needed for generating the second waveform. The method also includes, based on the first and second integer command signals, mapping to each branch a number of cell states to be used for concurrently generating both the first and second waveforms, generating branch-level command signals to a capacitor voltage balancing algorithm. The method also includes, based on the mapping and the balancing algorithm, sending firing signals to the plurality of cells of each branch.

摘要： A phase converter that converts single phase AC electric power to balanced three phase AC power. Two input terminals are connectable to a single phase AC power source, and connect directly to two output terminals of the converter. The phase converter has a storage capacitor, three active half bridge modules connected to the storage capacitor and a controller. Two modules connect to the input terminals and charge the storage capacitor. The other module connects to a third output terminal. The controller switches the module connected to the third output terminal and one of the other modules to generate and shape a second phase and a resultant third phase.

摘要： A power switch apparatus for a power converter includes a semiconductor power switch and a gate drive unit connected to the semiconductor power switch for supplying gate drive signals to the semiconductor power switch to switch it on and off to cause the power converter to generate an alternating current voltage having a nominal operational frequency based on command signals received from a controller. The gate drive unit receives command signals based on the AC voltage to be generated and to alter the switching events of the semiconductor power switch by addition of a pre-defined jitter-like deviation to the gate drive signals such as to cause the power converter to generate an AC voltage having a modified operational frequency which partly and temporarily deviates from the nominal operational frequency by a pre-defined minimum percentage. A power converter comprising such a power switch apparatus is also disclosed.

摘要： A bidirectional integrated CMOS switch is provided which is capable of switching voltages beyond the range of the supply and ground potentials. The switch is composed of NMOS and PMOS transistors as the switch conductor path, a diode bridge, and control circuitry to turn the switch on and off by means of low voltage logic, regardless of the voltages on the switch terminals. The device and method of the invention enables the switching of high voltage loads operating at arbitrary or floating voltages relative to the low voltage power supply and ground, and provides on/off control of the switch with ordinary low voltage logic levels. The invention provides bidirectional switching without conducting through the parasitic body diodes of the CMOS devices.
