A drive train system (DTS) powered by an ideal voltage source and driving a permanent-magnet synchronous motor (PMSM) is discussed in this paper. A two-level three-phase voltage source inverter is used as a means of power conditioning. This converter is not equipped with any harmonic filters on neither the ac nor the dc side. The mechanical part of the DTS is modeled as a double oscillator according...
A space vector based bang-bang controller driving a rotating target system (space vector bang-bang controller with flux related hysteresis shape SVBF) such as a machine or an ac-power-supply is discussed in this paper. A two-level, three-phase conventional inverter is used as means of power conversion. The advantages such as a low switching frequency as well as further opportunities of the SVBF are...
A drive train system (DTS) powered by an ideal voltage source and driving a permanent magnet synchronous motor (PMSM) is discussed in this paper. A two-level, three-phase conventional inverter with no harmonic filters on both AC and DC sides is used as means of power conditioning. This DTS is modelled as a double oscillator according to a drive train in an electric vehicle. Various inverter modulation...

Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
An improved delta modulation (IDM) controller for pulse width modulation (PWM) inverter is presented in this paper. The proposed IDM use the input reference signal to generate the variable integrating slope for the integrator in order to obtain better control ability. The proposed IDM can increase the modulation gain of the fundamental component, reduce the total harmonic distortion, expand the duty...
