Novel Fifteen-switch Three-level Dual-output Inverter Based on Single-leg Independent Model Predictive Current Control
摘要
Abstract
Aimed at the problems of a large number of switching devices and complex control strategy for an inverter in the multi-motor drive system of a 800 V high-voltage platform for electric vehicles,a fifteen-switch three-level dual-output inverter is proposed,which simplifies the inverter topology and reduces its cost by device multiplexing.First,a detailed analysis of the proposed inverter topology and working principle is performed,its structural characteristics are summarized,and the effective switching state and maximum voltage stress analysis are given,providing a theoretical basis for the selection of switching devices and system design.Then,a single-leg independent model prediction current control strategy is put forward,and a prediction model of single-leg dual-output port current is established,which effectively reduces the prediction operation under the premise of realizing three-leg independent prediction control and single-leg dual-output current integrated optimal control.Finally,the correctness and effectiveness of the proposed inverter and its control strategy were experimentally verified based on a Typhoon HIL 402 platform.关键词
