This document shows the scheme for controlling induction motor performance for certain transient conditions. The purpose of the work is for solving the problem of induction motor overloading and grid overloading too. A detailed approach is used for designing the system model with the concept of mechanical coupling within two motor drives. Therefore a DC motor is used which will mechanically be coupled...
This paper proposes a new power management strategy based on pq-Theory for fuel cell and electric vehicle applications. Using a modular cascaded converter topology, more than one power source could be combined with capacitors to supply active and reactive power in an efficient manner to the electric motor. The control strategy to separate mean and oscillating active power and reactive power, as well...
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...
In this paper, a new approach is presented for integrating the function of onboard battery charging into the traction drive system and accessory dc-dc converter of a plugin electric vehicle (PEV). The idea is to utilize the segmented traction drive system of a PEV as the frond converter of the charging circuit and the transformer and high voltage converter of the 14 V accessory dc-dc converter to...
The increasing trend of DC/AC induction motor converters implementation in a wide range of driving applications is becoming a fact that could not be neglected any more. This fact challenges the designers of the DC/AC induction motor converters to constantly seek performance improvements and cost reductions on an everyday basis. The paper describes some of the design improvements of a DC/AC induction...
The article discusses problem of energy flow in serial hybrid propulsion system with super-capacitor energy storage with respect to robust control and stabile behaviour of all the drive. The simulation model in MATLAB/Simulink of serial hybrid vehicle with super-capacitor is presented. Theoretical results are experimentally verified of physical model.
This paper presents a battery supplying a bidirectional Z-Source Inverter (ZSI) feeding a three phase induction motor. The indirect field-oriented control (IFOC) method is used to control the induction motor speed during motoring and regenerative braking operations. The IFOC is implemented based on PWM voltage modulation with voltage decoupling compensation. A dual loop controller is designed, based...
The power train of fuel cell vehicle adopts the hybridization with a fuel cell system and an energy storage system, which can be battery pack or super capacitor pack, in order to improve the fuel economy of the vehicle through regenerative braking and possibly to increase the specific power and to decrease the cost of the power train. The hybrid power train of fuel cell vehicle can be different depending...
A hybrid electric Kart is built as a didactical project for the students of the Master of Engineering: Energy of the K.U.Leuven. In order to cope with the growing number of students, a modular hybrid electric kart is conceived. The hybrid configuration allows to diversify between several tasks that have to be addressed by the students. The tasks include a control scheme for an induction motor, a control...
This paper describes a bidirectional DC-DC converter for a small electric vehicle. The DC-DC converter designed and tested is capable of raising the voltage from the battery pack (96 V nominal) to 600 V necessary to feed the variable frequency drive that controls the induction motor. This converter is also capable of working in the opposite direction (600 V to 96 V) in order to capture energy from...
