Question 3 3.1 3.2 3.3 A rectifier supplies 100 V to a load. Ignore overlap and other losses. The ripple factor in the load voltage is defined as the ratio of the total rms value of all the alternating components to the mean value. Thus +...+V² ripple factor: 介 V mean V² where V is the rms value of the total wave. rms V² 2π V² m 2π = V₁ = √√V.² +V² 1ms Vo = √²dt = √√₂ cos²ox dpox V rms π Jo 2 DC pa 1 = -T T + PV π (1+ cos2@t)dpot 5*(1 + cos2wt)dpat rms V 2 psin 25 msin T mean P T T Р nrms =V = V² m √2π| =V sin m √√2 V rms V T P + 2 4π π P V² m 2 (1+cos 2 wt) dpat pot + -V² mean -sin mean psin 2 ot 2 2π P Determine the ripple factor of a single-phase bridge rectifier 2-pulse: Determine the ripple factor of a three-pulse zig-zag rectifier. 3-pulse: Determine the ripple factor of a three-phase bridge rectifier. 6-pulse: (2) (2) (2) [6] Question 3 3.1 3.2 3.3 A rectifier supplies 100 V to a load.
