The asymmetrical half-bridge converter (AHBC) has the attractive features of zero voltage switching (ZVS) and voltage clamping. However, the converter is not suitable for wide input voltage range applications since it has the problem of a 50% maximum allowable duty cycle. A new AHBC topology with a tapped output inductor filter is proposed that not only(More)
—In this paper, a new approach which differentiates from the conventional thinning algorithms in vectorizing a raster line image called maximal inscribing circle (MIC) is used. This region-based vectoriz-ation algorithm takes the ensemble of pixels within the line segments collectively as legitimate candidates in deciding the vectorized representation. An(More)
