| Summary: | An analysis and implementation of delta modulation (DM) technique in the control
of ac-dc converters is studied here in this project. The DM technique offers advantages of
easy implementation, continues converter voltage control, and a direct control on the line
harmonics. A simple circuit of the delta modulator is proposed, designed and fabricated in
the laboratory. This proposed modulation scheme, fundamentally differs from conventional
PWM technique, by virtue of its self carrier generating ability. Results of the parametric
variation of the modulator are reported. Simulated and experimental results of the single
phase DM ac-dc converters validate the analytical results. |
