ABSTRACT
 This paper mainly handles about the designing of the inverter and the controller to drive the BLDC motor for the small electric vehicle. The speed control part of driving system is designed to select the usage of 32 bits DSP(TMS320F2808) specialized for a servo motor control and 16 bits Microchip’s micro-processer(dsPIC30F2010) optionally. The inverter driving part is designed with the MOSFET(IRFB3077) which is capable of high speed switching and better for low voltage batteries switching. Instead of using complicated PWM(Pulse width Modulation) method, we used simple 3 phase, 2 excitation PWM method having 6 step excitation sequence and voltage controlled PWM method to reduce the load of a software. The digital control algorithm for the speed control is simplified to control the speed by controlling voltage right away not performing current control. Through the result obtained from the driving of the BLDC motor by using the suggested hardware controller and algorithm for speed and PWM, we proved the usefulness of the hardware controller and control algorithm. KEYWORDS BLDC motor, electric vehicle, inverter, micro-processer, MOSFET, PWM, control algorithm.

 Abstract
With fast rotating permanent-magnet motors and compact battery storage units, the high performance motorsport community has, in recent years, started to utilize the quick response and high torque of electrical drivetrain solutions. By recovering energy, braking into a corner, for then to utilize the same energy, boosting out again, the electrical machine gives increased performance even for the fastest racing cars. The purpose of the work presented in this Master’s thesis is to develop and produce the power electronics and motor control system needed to control such an electric machine, where the final product is used to drive a fully electric prototype racing car. The thesis presents the conceptual work, design choices, prototyping, testing and development of a 2-level voltage source inverter and motor control system. The voltage source is a battery accumulator energy storage unit, while the machine is a three-phase permanent-magnet motor. The voltage source inverter is based on insulated-gate bipolar transistors (IGBTs), controlled by a motor control system called field oriented control. On command from the driver’s throttle, the motor control system generates the required stator currents, giving the wanted output torque, supplied from the voltage source of the battery accumulator. The inverter is the connecting interface between the power source, and the rotating machinery. With the amount of energy and power needed to drive a racing car, safe and reliable operation is important. To ensure the safety of the driver and operating personnel, the system and its safety features have been through extensive testing in a laboratory setup and on the race tracks. In the system development process, simulation and modelling tools have been applied to investigate different solutions and technologies. These tools have also been used to design the electric circuits, program code and mechanical design needed for the system. The final product is installed in a racing car and shows great performance.

 Abstract – In order to solve the neutral-point voltage fluctuation problem of three-phase threelevel T-type inverters (TPTLTIs), the unbalance characteristics of capacitor voltages under different switching states and the mechanism of neutral-point voltage fluctuation are revealed. Based on the mathematical model of a TPTLTI, a feed-forward voltage balancing control strategy of DC-link capacitor voltages error is proposed. The strategy generates a DC bias voltage using a capacitor voltage loop with a proportional integral (PI) controller. The proposed strategy can suppress the neutral-point voltage fluctuation effectively and improve the quality of output currents. The correctness of the theoretical analysis is verified through simulations. An experimental prototype of a TPTLTI based on Digital Signal Processor (DSP) is built. The feasibility and effectiveness of the proposed strategy is verified through experiment. The results from simulations and experiment match very well.

 1. Introduction
 Currently, the production of domestic and industrial energy is based, in large part, on a limited resource: oil. Oil sources are becomingmore andmore rare, while the energy demands of the world rise continually. Since this formof energy covers a large part of the current energy production, it is necessary to find another solution to take over.The imposed constraint is to use an energy source that is economical and less polluting because the protection of the environment has become an important point [1–3]. The search for alternative energy resources has therefore become a crucial issue these days. Many scientific researches have been carried out, not only in the field of nuclear energy production, but also in the sector of unlimited energy sources, such as wind power generation and energy transformation. In the latter case, the design, optimization, and realization of photovoltaic systems are topical issues since they lead to a better exploitation of solar energy [2]. These photovoltaic powers generating systems can be operated in different places: electrification of isolated sites, installation in buildings or direct connection to network of electricity, and so on. A major problem with PV systems is to realize transfer of maximum power from PV generator to load. For several years, manyMPPT controlmethods have been developed and implemented, like Fuzzy Logic Method [4–7], perturbation and observation (P&O) method [5, 6, 8], and Incremental Conductance (Inc.Con.) method [7, 9–11].These techniques are generally complex and expensive to implement [4, 9, 12]. They differ in several aspects like complexity, range of effectiveness, cost, convergence speed, implementation hardware, required sensors, and popularity, plus other respects. However, these techniques are digital implementation. Alternatively, the MPPT can be implemented by analog circuits [13–15]. The potential benefit from analog solution is that theMPPT can be integrated withDC-DCcontroller such that “plug and play” can be expected for many low power PV applications. In fact, integration of certain functions into a normal PWM controller chip is the most desirable way for special applications to reduce the implementation complexity and system cost. In this paper, a new analog MPPT technique suitable for PV system applications is presented and validated by simulations.
