Winding-Based Discharge Technique Selection Rules Based on Parametric Analysis

In the previous chapters, several winding-based discharge strategies have been introduced, which include the traditional LDA-CI method, piecewise NDNQ method, hybrid discharge scheme and indirect current regulation-based methods. However, a crucial problem is that when designing the discharge system for a particular EV, there are no ready-to-use rules that an engineer can follow to pre-evaluate whether or which winding-based discharge technique is available, especially for the high-speed range. To solve this challenge, this chapter proposes general principles for picking out applicable winding-based DC-bus capacitor discharge techniques at the stage of EV design on the basis of parametric analysis. Then, case studies are used to verify the proposed discharge technique selection rules.
