Aiming at the problem of low efficiency of recycling energy in the process of regenerative braking for electric vehicle, SVPWM algorithm is applied to the process of energy transformation of regenerative braking in this paper. It is derived and verified that, through using SVPWM, DC voltage fluctuation can be reduced in the process of rectification. The simulation model is built basing on the Volkswagen LAVIDA EV. The simulation experiment was carried out combining with the actual working status of electric vehicle regenerative braking. The simulation experimental results prove that DC voltage fluctuations can be decreased and the efficiency of regenerative braking rectifier can be increased through SVPWM. The following feature of rectifier in the braking condition is good.

Fault Ride Through

Due to the increase in DC load and DC Power generation, the need for DC power system is emerging. Accordingly, FRT (fault ride through) and LVRT (low voltage ride through), which are related regulations for renewable energy sources, have been enacted, and operation algorithms of each converter are required for this. However, the operation of the converter according to LVRT regulations causes DC voltage fluctuations. In the current study, DC voltage fluctuation is suppressed through converter control of DC-linked battery. The controller was designed from the relational equation between DC voltage and instantaneous power of battery. The pattern of DC voltage fluctuations to the output of the PV (photovoltaic), which is a DC power generation source, was confirmed, and voltage fluctuation suppression was verified by applying the designed converter cooperation algorithm and controller.

Operational Modes

The paper deals with a novel enhanced connection of AC/AC powertrain for HEV hybrid vehicles. The substantial contribution of such a connection is the absence of 4QC auxiliary converter needed for autonomous and hybrid operational modes and its compensation by power-lesser 0×5 matrix converter. The main advantages of a simplified connection are beside smaller auxiliary converter sizing and possible better efficiency of the HEV powertrain. So, powertrain operation in autonomous traction accu-battery modes uses direct 0×5 configuration of traction 3×5 MxC matrix converter and in hybrid modes of ICE engine and accu-battery, besides traction 3×5 MxC matrix converter, uses the auxiliary 0×5 matrix converter. Modeling and simulation using Matlab-Simulink environment of traction powertrain configuration in autonomous modes are presented in the paper, as well as all simulation experiment results.
