摘要

This article is subject to the improvements made over an emergency DC injection braking system for AC motors. The modifications put in place a bi-directional braking circuit capable of flowing the power into the traction system in one direction or recharging the battery in the other. We applied the proposed topology over a specific need: automotive application like HEV, EV and electric motorcycle. With the use of the new semiconductors and computing power, we were able to design a compact and reliable braking system with a low part count. The reduce time and enhance current control make this topology a perfect candidate for a redundant braking unit. A simulation of the system with a well evaluated load will be presented. Our paper will discuss also the advantages and drawbacks of this method.
