A hybrid, current-source/voltage-source power inverter circuit
IEEE Transactions on Power Electronics, 2001A combination of a large current-source inverter and a small voltage-source inverter circuits is analyzed. The resultant hybrid inverter inherits certain operating advantages from both the constituent converters. In comparison with the popular voltage-source inverter, these advantages include reduced switching losses, improved quality of output current

Voltage control of current source inverters
IEEE Transactions on Energy Conversion, 2006The current source inverters may become direct competitors of the voltage source inverters thanks to the voltage control techniques. The paper proposes an improved voltage control technique for current source inverters, that chooses the current vectors relying on bang-bang controllers.

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.

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 ...

The tandem inverter: combining the advantages of voltage-source and current-source inverters
APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition, 2002A combination of a current-source primary inverter and a voltage-source secondary inverter is proposed as the so-called tandem inverter. The primary inverter operates in the square-wave mode, handling most of the converted power, while its output harmonic currents are compensated by the much smaller secondary inverter. As a result, the tandem inverter,
