In order to utilize the energy from the renewable energy sources, power conversion system is necessary, in which the voltage source inverter (VSI) is usually the last stage for injecting power to the grid. It is an economical solution to add the function of power quality conditioning to the grid-connected VSI in the low-voltage distribution system. Two multifunctional VSIs are studied in this p...

The width of an interconnect line affects the total power consumed by a circuit. A trade off exists between the dynamic power and the short-circuit power dissipated in inductive interconnect. The optimum line width that minimizes the total transient power dissipation is determined in this paper. A closed form solution for the optimum width with an error less than 5% is presented. For a specific...

Addressing the need for passive magneto-inductive components, a lumped-element symmetric power divider has been designed and realised for a magneto-inductive cable with the resonant frequency of 95 MHz and the passband between 73 and 174 MHz. In agreement with the theory, the measured coupling loss is 6 dB for most of the passband independent of the input port. Having proved useful for magneto-...

At velocities below 100 km/h and during stops the Transrapid vehicle has to be supplied with energy by an external source for the on board power consumers like levitation magnets and climate control. A new contactless inductive power supply system, IPS, was developed for the German Transrapid project in Munich on behalf of the BMVBS. With IPS the power supply will work without mechanical contac...

We report upon a recently developed long range inductive power transfer system (IPT) designed to power remote sensors with mW level power consumption at distances up to 7 m. In this paper an inductive link is established between a large planar (1 x 1 m) transmit coil (Tx) and a small planer (170 x 170 mm) receiver coil (Rx), demonstrating the viability of highly asymmetrical coil configurations...

The paper presents a computer analysis of inductive coupling of the electromagnetic compatibility (EMC) problem. Its focus is on power electronics and electrical drives and tests performed by a numerical computer simulation that can disclose suite surprising findings about EMC.

Ionic polymer metal composite (IPMC), of which a low actuating voltage (<5 V), high power efficiency and biocompatibility makes it a proven candidate for low power devices. However, due to its inherent nonlinear behaviour and time-variance, feedback control, as well as reliable sensing means, are required for accurate operations. This paper presents an IPMC actuator implemented with an inductiv...
