Abstract
This study aims to compare high-side and synchronous trapezoidal brushless DC (BLDC) control methods using an XMC-based motor controller for pedelecs. The electric bicycle implemented three different pedal-assist modes with varying human-tomotor power ratios and one throttle mode with the use of proportional integral control. The study compares the efficiencies of two trapezoidal control methods through the throttle and pedal-assist mode. The data obtained shows that the high-side trapezoidal control is more efficient than the synchronous trapezoidal control in all modes implemented on the e-bike. This research opens possibilities to improve other BLDC control algorithms especially in terms of efficiency.
