20140184315 | PARALLELING OF ACTIVE FILTERS WITH INDEPENDENT CONTROLS - A parallel filter arrangement with at least two filters supplying current in line side sensing configuration and a number of sensors for measuring current. The sensors are used to determine the amount of current being supplied by the filters and the amount of current being supplied by a source. The filters adjust their supplied current in order to reduce or eliminate the amount of reactive or harmonic current being supplied by a source. | 07-03-2014 |
20150091640 | RECONFIGURABLE PASSIVE FILTER - A passive filter for connection between an AC source and a load, in either three-phases or in a single-phase arrangement. The filter includes, for each phase, a trap circuit having an inductor in series with a capacitor, the trap circuit having at least two terminals. A line reactor is connected between the AC source and the load, the line reactor having at least an input terminal, an output terminal and a tap terminal. A switch selectively connects at least one of the trap circuit terminals to a selected one of the line reactor terminals. The switch is capable of selecting which of the trap circuit terminals to connect to which of the line reactor terminals on the basis of a level of voltage distortion being experienced by the AC source, or on the basis of a calculated level of background voltage total harmonic distortion. | 04-02-2015 |

20080298103 | FOUR POLE NEUTRAL-POINT CLAMPED THREE PHASE CONVERTER WITH LOW COMMON MODE VOLTAGE OUTPUT - A four pole, three-phase, NPC converter that produces virtually no common mode voltage. The low common mode voltage output is achieved by constraining the switch states of the NPC converter. A fourth pole and associated control balance the upper and lower DC link voltages. The converter may be an inverter or a rectifier. | 12-04-2008 |
20100085789 | Voltage Drive System With Hysteretic Current Control And Method Of Operating The Same - A voltage drive system is provided having a plurality of modulators and a plurality of cascaded switching circuits which collectively generate a single-phase output signal to a load. Each modulator receives a phase current error and has an adder which generates a modulated phase current error based on the phase current error and based on a signal having a phase. For each respective modulator, the phase of the respective signal is different. Each respective modulator changes a respective gate input when the respective modulated phase current error changes from being within a predetermined current range to being outside of the predetermined current range. Each respective switching circuit receives the respective gate input and generates a respective output terminal voltage based on the respective gate input. The change in the respective gate input effectively causes a switching event of the respective switching circuit. | 04-08-2010 |
20100165688 | CASCADED FLYING CAPACITOR MODULAR HIGH VOLTAGE INVERTERS - A high voltage inverter is provided which includes a plurality of k-level flying capacitor H bridge modules, k being greater than 2, each having a positive dc terminal, a negative dc terminal, and two ac terminals, a connecting unit for connecting said ac terminals of said plurality of k-level flying capacitor H bridge modules in series to form a cascading set of modules, and a dc source connected to an ac source and having a transformer, a rectifier rectifying an output voltage of said transformer, and a capacitor connected between the positive and negative dc terminals. | 07-01-2010 |
20130051094 | CASCADED FLYING CAPACITOR MODULAR HIGH VOLTAGE INVERTERS - A high voltage inverter is provided which includes a plurality of k-level flying capacitor H bridge modules, k being greater than 2, each having a positive dc terminal, a negative dc terminal, and two ac terminals, a connecting unit for connecting said ac terminals of said plurality of k-level flying capacitor H bridge modules in series to form a cascading set of modules, and a dc source connected to an ac source and having a transformer, a rectifier rectifying an output voltage of said transformer, and a capacitor connected between the positive and negative dc terminals. | 02-28-2013 |
20130314953 | HARMONIC REGULATOR FOR CURRENT SOURCE RECTIFICATION AND INVERSION - A system includes a current source rectifier which has a plurality of switches configured to receive an input current from an AC voltage source and to receive a plurality of control signals. The switches are configured to produce a rectified output current based on the input current and the control signals. The system also includes a rectifier controller configured to receive a current sense signal indicative of the rectified output current and to generate the control signals based at least in part on the current sense signal, where the control signals cause the current source rectifier to attenuate at least one of a plurality of harmonic frequencies in the rectified output current. | 11-28-2013 |
