An Overmodulation Method for Space Vector PWM Current Source Inverters

摘要：

Operating current source inverters (CSI) in the overmodulation range extends their current and power ranges as the voltage source inverters do. This paper presents a simple overmodulation algorithm for space vector pulse width modulation (PWM) suitable for CSI. The proposed algorithm views the operation area as a whole, and allows smooth transitions through the entire operating range up to six-step operation. In addition, harmonic components of the output current is analyzed. When the technique is applied to the CSI-based uninterruptible power supplies (UPS), quicker dynamic response and higher output power are obtained, and a smooth operation during transition between the linear control range and the six-step mode is also demonstrated through simulation results.
