Systems And Methods For Switch-Controlled Var Sources Coupled To A Power Grid

View page
US Patent:
20130138260, May 30, 2013
Filed:
Dec 6, 2012
Appl. No.:
13/707560
Inventors:
Hao Chen - San Jose CA, US
Anish Prasai - San Jose CA, US
Assignee:
VARENTEC, INC. - San Jose CA
International Classification:
G05B 13/02
US Classification:
700298
Abstract:
Systems and methods for switch-controlled VAR sources coupled to a power grid are described. In some embodiments, a system comprises a distribution power network coupled to a first switch-controlled VAR source. The first switch-controlled VAR source may comprise a processor, a voltage compensation component, and a switch. The first switch-controlled VAR source may be configured to obtain a first delay value, monitor a first proximate voltage, initiate a first delay duration based on the comparison of the first proximate voltage to at least one set point, the first delay duration being based on the first delay value, determine, with the processor, after the first delay duration, whether to connect the voltage compensation component based on the monitored voltage, and control, based on the determination, the switch to connect the voltage compensation component to adjust a network voltage or a network voltage component.

Compact Dynamic Phase Angle Regulators

View page
US Patent:
20130140903, Jun 6, 2013
Filed:
Dec 6, 2012
Appl. No.:
13/707558
Inventors:
Deepakraj M. Divan - San Jose CA, US
Anish Prasai - San Jose CA, US
International Classification:
H02J 3/01
US Classification:
307 82
Abstract:
Compact dynamic Phase Angle Regulators (CD-PARs) are provided. A Compact Dynamic Phase Angle Regulator (CD-PAR) is a stand-alone device that regulates phase angle through a single transformer. A CD-PAR has no external energy source, uses low-rating devices, and can be isolated from a fault in the grid. A CD-PAR may be implemented in a single-phase or in a three-phase configuration, but the operation of a CD-PAR cross-couples all three phases. A CD-PAR controls both the real and the reactive power flow between two AC sources having the same frequency by inserting a voltage with controllable magnitude and phase. A CD-PAR may be implemented in either a buck configuration or a boost configuration.

Systems And Methods For Harmonic Resonance Control

US Patent:
20130173078, Jul 4, 2013
Filed:
Dec 6, 2012
Appl. No.:
13/707583
Inventors:
Anish Prasai - San Jose CA, US
Assignee:
VARENTEC, INC. - San Jose CA
International Classification:
G05F 5/00
US Classification:
700295
Abstract:
Systems and methods for harmonic resonance control are described. In some embodiments, a system comprises a first switch-controlled VAR source and a harmonic management block which may each be configured to be coupled to a distribution power network. The first switch-controlled VAR source may comprise a first processor, a voltage compensation component, and a switch. The first processor may be configured to enable the voltage compensation component after a delay by controlling the switch based on first proximate voltage after a duration associated with the delay to adjust voltage volt-ampere reactive. The harmonic management block may be configured to compare a second proximate voltage to at least one resonant threshold to detect potential resonance caused by enablement of the voltage compensation component and to engage based on the comparison the resonance compensation component to manage the potential resonance.

Isolated Dynamic Current Converters

View page
US Patent:
20130201733, Aug 8, 2013
Filed:
Dec 24, 2012
Appl. No.:
13/726524
Inventors:
DEEPAKRAJ M. DIVAN - San Jose CA, US
ANISH PRASAI - San Jose CA, US
HAO CHEN - San Jose CA, US
International Classification:
H02M 1/00
H02M 1/12
H02M 7/42
H02M 7/02
H02M 5/00
US Classification:
363 39, 363123, 363126, 363 37, 363131
Abstract:
Isolated Dynamic-Current (“Dyna-C”) converters are converters that convert incoming 3-phase AC or DC power to a mix of DC and AC power via an isolation link. In various embodiments, the isolation link is a high-frequency isolation transformer. Isolated Dyna-C converters may provide a high-frequency galvanic isolation and are able to convert three-phase AC power to three-phase AC power, or three-phase AC power to DC and vice versa. The topology is minimal and the costs are low. Isolated Dyna-C converters provide fast current responses and keep the losses low by using a simplified two-stage conversion and providing a magnetizing current that is dynamically controllable and tailored to the load. An isolated Dyna-C converter may synthesize currents at its input or output ports with an arbitrary phase that is relative to the grid or load voltages, thereby enabling a full independent control over the active and reactive power at its ports.

Imputed Dc Link (Idcl) Cell Based Power Converters And Control Thereof

US Patent:
20130207471, Aug 15, 2013
Filed:
Feb 1, 2013
Appl. No.:
13/757731
Inventors:
DEEPAKRAJ M. DIVAN - San Jose CA, US
ANISH PRASAI - San Jose CA, US
JORGE HERNENDEZ - Smyrna GA, US
ROHIT MOGHE - Atlanta GA, US
AMRIT LYER - Atlanta GA, US
RAJENDRA PRASAD KANDULA - Atlanta GA, US
International Classification:
H02J 3/00
US Classification:
307 43
Abstract:
Power flow controllers based on Imputed DC Link (IDCL) cells are provided. The IDCL cell is a self-contained power electronic building block (PEBB). The IDCL cell may be stacked in series and parallel to achieve power flow control at higher voltage and current levels. Each IDCL cell may comprise a gate drive, a voltage sharing module, and a thermal management component in order to facilitate easy integration of the cell into a variety of applications. By providing direct AC conversion, the IDCL cell based AC/AC converters reduce device count, eliminate the use of electrolytic capacitors that have life and reliability issues, and improve system efficiency compared with similarly rated back-to-back inverter system.
