Summary: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 | Summary:The authors describe the design, construction, and testing of an all n-channel PWM (pulsewidth modulation) DC-DC converter for electric wheelchair (EW) applications.

Summary:The majority of electric wheelchair users are able to operate a joystick to control the chair, however many more quadriplegic users need some other means of controlling the wheelchair. This paper describes an electronic PWM DC drive unit designed for operation by standard joystick, ultrasonic noncontact head control, and by command from a limited speech vocabulary | Summary:The majority of electric wheelchair users are able to operate a joystick to control the chair, however many more quadriplegic users need some other means of controlling the wheelchair.
