In this paper, an application of voltage differencing voltage transconductance amplifier (VDVTA) in the realization of voltage-mode (VM) multi-input single output (MISO) type biquad is presented. The proposed topology uses one VDVTA as an active element, two capacitors and a grounded resistor. The configuration realizes low pass (LP), high pass (HP), band pass (BP) and notch (BR) filters withou...

Abstract In this paper a promising novel output voltage filtering concept for multi-cell switch-mode power amplifiers is analyzed. The proposed hybrid filtering concept is based on a passive LC filter enhanced by a linear-mode correction stage of small rated power. Using this principle, also "sub-harmonic" (i.e. low-frequency) switching noise distortions (typically appearing in real interleaved...

The work presented in this paper proposes an approach to reduce the common mode voltage at the output of matrix converters when a direct torque control scheme is employed to drive a permanent magnet synchronous motor. A mathematical analysis of the common mode voltage at the output of matrix converters is firstly carried out which is then corroborated by simulation results. Based on this analys...

In this paper, a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive load is obtained. Then, the control law is designed using sliding mode techniques. The controller introduces a dynamic extension so that the stator voltage amplitude has relat...

Switched reluctance (SR) motors have high power density, high efficiency, high reliability, high fault tolerance, and low manufacturing cost. Thus, these motors have a high potential than other machines such as permanent magnet brushless motor, high-temperature super conductor motor, etc.; hence, it is well-suited for electric marine propulsion. This paper presents a new power converter and ana...
