A Novel Metamaterial Microelectromechanical Systems Phase Shifter with High Phase Shift and High Bandwidth

In this paper, new topology of phase shifter is proposed that uses advantage of metamaterial and MEMS technology. The phase shifter is switched between two states of RH- and LH-TL having frequency passband unlike other proposed metamaterials which create the maximum phase shift from one unitcell. Analysis and design approach of the phase shifter is presented and the structure is simulated using...

A Novel and Simple Current Controller for Three-Phase IGBT PWM Power Inverters - A Comparative Study

A new feedback current controller for three-phase pulse width modulated power inverters is presented. To achieve robustness against load parameter variation, fast dynamical response, reduced switching frequency and simple hardware implementation, a three-level hysteresis sliding mode controller is used. The voltage vectors applied to the load are accurately selected in order to minimise the cur...

A Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory

This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...

A Novel and Simple Current Controller for Three-Phase IGBT PWM Power Inverters

A new feedback current controller for three-phase pulse with modulated power inverters is presented. It is based on a current loop with two non linear three-level hysteresis controllers. The voltage vectors applied to the load are accurately selected in order to minimise the output current error. Controller structure based on simple analog-digital hardware implementation is shown and experiment...
