Dedicated wide band current transformers exist. However, in this paper, an evaluation is made of the characteristics of a current transducer based on a standard available common mode filter inductor. Based on the inductance and resonance frequency, a frequency span of 0.5 Hz up to 50 MHz can be achieved. The performance is possible by the fact that the used amorphous materials have a very high permeability and that the resonances of the windings at high frequency can be controlled. The following limitations are discussed: by saturation at low frequency and DC components, due to the load resistance, due to eddy currents and of the inserted primary conductor.

This paper investigates an improved 3-level flying capacitor inverter topology allowing a drastic reduction of reverse recovery related losses. It benefits from the latest superjunction (SJ) MOSFET devices. The presented 2kW inverter was designed for Japanese PV market (200Vrms). It allows non unitary power factor operations with peak and European efficiency of 98.0% and 97.6% respectively. Thanks to SJ MOSFET implementation, it outperforms state-of-art configuration using IGBTs and SiC diodes in terms of efficiency.
