Efficient Snubbers for Voltage-Source GTO Inverters

IEEE Transactions on Power Electronics, 1985
The two gate turn-off thyristors in the phase leg of a voltage-source inverter are provided with a series center-tapped inductance snubber and shunt capacitor snubbers having a single discharge resistor and only two auxiliary diodes. This arrangement minimizes the number of components and allows reduction of capacitor size, thereby reducing the snubber

Parallel operation of voltage source inverters

IEEE Transactions on Industry Applications, 1988
Parallel operating systems of voltage source inverters with other inverters or with the utility source are sensitive to disturbances from the load or other sources and can easily be damaged by overcurrent. Thus extremely careful attention should be given to the system design of parallel operating inverters.

Evolution of multilevel voltage source inverters

2008 9th International Conference on Actual Problems of Electronic Instrument Engineering, 2008
The problem of increase in power and voltage of inverters today is provided more often by construction of multilevel voltage source inverters. The formation of an Instant curve of voltage of such inverter goes basically by the amplitude modulation with PWM added between the neighboring levels of the voltage of amplitude modulation.

Inverter for Interchangeable Use as Current Source Inverter and Voltage Source Inverter for Interconnecting to Grid

IEEJ Transactions on Industry Applications, 2011
AbstractWe propose a novel inverter that can be operated either as a current source inverter (CSI) or as a voltage source inverter (VSI) by changing only the control signals. It is proper to use it for interconnecting systems with renewable energy, such as photovoltaic cells or wind generation systems, to a grid.

Pulse-Width-Modulated Voltage-Source Inverters

1993
In a pulse-width-modulated inverter, each half-cycle of the output voltage is made up of several square pulses of suitable width, instead of only one square-wave as was the case in the previous chapter.

High-Performance Voltage Regulation of Current Source Inverters

IEEE Transactions on Power Electronics, 2010
Current source inverters (CSI) offer advantages of voltage boost, short-circuit protection, reduced electromagnetic interference, and direct regeneration. While CSI control strategies are less developed than for voltage source inverters (VSI), the topologies are functional duals and have much in common in a control sense.

Current regulator instabilities on parallel voltage-source inverters

IEEE Transactions on Industry Applications, 1999
Parallel inverters are often used to meet system power requirements beyond the capacity of the largest single structure. They have also been used to reduce harmonics, reduce pulsewidth modulation (PWM) switching frequency and increase available output voltage or frequency.
