This paper deals with a new PWM control scheme of matrix converters, which have been proposed by the authors. The PWM control scheme is characterized by the calculation algorithm using pseudo inverse and the performance that the output voltage can be controlled completely even if the input voltage is distorted. An experimental system, which consists of a matrix converter main circuit and a control...
Allowing a significant reduction of capacitor volumes as well as scalable in terms of voltage levels and control flexibility, stacked flying capacitor inverter has gained great industrial attention recently. However, it also needs to ensure balancing flying capacitor voltages under all operation conditions. A novel PWM method is proposed for stacked flying capacitor multilevel inverter to control...

This paper presents the design of a prototype distribution static compensator (D-STATCOM) for load compensation in an unbalanced distribution system. The D-STATCOM is intended to replace the widely used static VAr compensator (SVC). The compensation scheme of the D-STATCOM is derived using the symmetrical component method. In this work, the 12-pulse D-STATCOM configuration with IGBT has been designed...
This paper presents an investigation into the effects of timer jitter on the accuracy of measured results when using a digital signal processor card in a PC based measurement system. These results are particularly applicable for drive system engineers. Jitter is the error between the ideal sampling period and the actual sampling period. Timer jitter has different effects on the accuracy of the measured...
