Inhalt:
This paper presents the design and implementation of a converter topology to generate voltage excitations for COSS loss characterizations in MHz-frequency power switching devices. The assembled converter can drive a Sawyer Tower circuit with trapezoidal and sinusoidal voltage waveforms, up to 1.2 kV (PP) at MHz frequencies. Our work is intended to reduce the size and cost of existing characterization systems, improving access to COSS data.
