Improved voltage regulation for current-source inverters
IEEE Transactions on Industry Applications, 2001Voltage regulation schemes for current-source inverters (CSIs) commonly use a simple proportional-integral (PI) stationary frame controller, but this approach is known to suffer from significant steady-state error. In contrast, the more advanced schemes that are routinely used for current regulation of voltage-source inverters (VSIs) avoid these ...

Virtual Oscillator Control for voltage source inverters
2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013This paper summarizes a suite of methods that have recently been proposed for the control and synchronization of parallel single- and three-phase voltage source power electronics inverters. Inspired by the phenomenon of synchronization in networks of coupled oscillators, the premise of the proposed Virtual Oscillator Control (VOC) is to control an ...

Analysis of current controllers for voltage-source inverter
IEEE Transactions on Industrial Electronics, 1997Current-controlled pulsewidth modulated (PWM) inverters are widely used in high-performance AC drives because they give high dynamic responses in such systems. This paper presents a comparative study of several current controllers. Particular attention is paid to the hysteresis controller and the ramp-comparator controller, due to their simplicity and ...

Effect of supply-voltage unbalance on voltage-source inverter
3rd IET International Conference on Power Electronics, Machines and Drives (PEMD 2006), 2006Properties of the control method for the compensation of unbalanced voltage supply that eliminates pulsating current in the DC bus of a voltage source inverter are analyzed. These pulsations can have negative effects on operating properties of the drive as well as on the quality of power supply in the electrical vicinity of the inverter.

Efficient Snubbers for Voltage-Source GTO Inverters
IEEE Transactions on Power Electronics, 1985The 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
