摘要：

This paper presents a comparison between analog and digital (PIC16c73a) control types applied to the boost converter with a nondissipative snubber. Both control types use the bang-bang hysteresis current waveshaping control technique in order to achieve a quasi-unity power factor. The analog control applied presented a high power factor (0.998), high efficiency (92.87%), and low harmonic distortion [total harmonic distortion of current (THDI = 2.84% and total harmonic distortion of current (THDV) = 2.83%)]. The digital control presented a high power factor (0.990), high efficiency (92.46%), and low harmonic distortion (THDI = 5.09% and THDV = 2.84%).
