The authors describe the design, construction, and testing of an all n-channel PWM (pulsewidth modulation) DC-DC converter for electric wheelchair (EW) applications. The circuit requires only three ICs and four power MOSFETs, plus a few passive components. Its efficiency is much higher than that of a previously reported device that used n- and p-channel MOSFETs. The converter is compact, lightweight, and very reliable, owing to the use of ICs and a very low component count
