Due to the function of conventional PWM inverters, additional bearing currents appear. As counter- measures, passive filter components and advanced control methods have been proposed [2]. Furthermore, some other configurations of the converter, like neutral point clamped inverter, are able to provide common mode free output voltages under some restrictions in the modulation scheme. Recently Mohan...
This paper presents a new time-discrete predictive current control for permanent-magnet synchronous motor (PMSM) which follows a reference step in two sampling periods. The control stands out by using a permanent identification which allows fast control even if the motor parameters are changing. The identification analyzes the current response of each switch state of the voltage source inverter. This...
Controlling of a specific harmonic by a switching converter with switching frequency lower than 1 kHz was originally implemented by two-level optimal pulse pattern with unsymmetrical switching angles, namely by OPUS-technique. That means, given a desired fundamental and one or more specific harmonics, the problem is to find the switching times (angles) that produce the fundamental while generating...
