Abstract
The paper deals with the direct AC-AC propulsion system and compares two matrix converter concepts with fivephase traction induction motors (IM) for the hybrid electric vehicle (HEV) including electronic differential. The first one consists of [3x5] matrix converter and [3x1] active PWM rectifier (4Q-converter) for full power performance. The second one comprises one [3x5] matrix converter for full power and auxiliary [0x5] matrix converter for partial output
 power. Configurations of [3x5] + [0x5] MxC converters with five-phase motor(s) are not analyzed in available literature so far. The advantage of the proposed connection is in supposed higher efficiency of matrix converter then clasiccal VSI one. Part I deals with a theoretical study of converter concepts for hybrid electric vehicle. Based on simulation results the comparison and evaluation of the property and quality of the quantities of different type of the matrix powertrain are discussed in Part II.
Highlights
The mostly series hybrid electric vehicle (HEV) powertrains use front-end converter system with a DC-voltage interlink [1,2,3,4,5]
One of the important questions is the number of phases of the generator and/or traction motor, respectively
The configuration of novel simplified AC/AC powertrain shown in Figure 2 can be applied for following possible operation modes [6, 18]: a. traction drive/brake from/to ICE engine: ICE->>SG
Summary
The mostly series HEV powertrains use front-end converter system with a DC-voltage interlink [1,2,3,4,5]. Advantages and operation of a five-phase induction motor are described in [14], its operation under loss of one phase of a feeding source in [15]. Such a configuration of the AC/AC powertrain makes it possible both pure electric operating modes and/or pure engine mode, as well as hybrid mode: the vehicle is propelled by ICE engine and accu-battery energy in parallel operation [1]. The mostly powertrains with matrix converters use [3x3] MxC with three-phase IM/SM motors [8, 16,17], except for the author works [6, 18,19] and partially [8]. The [0x5] MxC (with partially power) is supposed for parallel operation only, so, the total operational efficiency should be higher
