Recearch and Development Engineer


Ankara, Turkey


Dear Sir, Works which will be achieved on Project: EXPERIENCE: Motor control experience: I have 4 year experience DSP implementation (TMS320C31 and TMS320P16, Texas Instruments) which is about the induction motor control. Vector control technique is applied to control speed and torque of motor from low speed to 2xnominal speed. The control system consist of 3 type modulation techniques, measuring current and voltage of motor, flux estimation algoritms by using several types control technique (Kalman filter, integration techniques, filters, PI control and observers). Analog design and smps experience: And also 4 year experince about smps, battery charger, analog design. I have designed li-ion battery charger (PWM ... morecontroller,TL494, Texas Instruments, constant current and voltage control), 140V/24V DC-DC converter (Elance project, you can see it in my profile, the level of output voltage can be controlled by using PIC microcontroller, 250 W), 28V/20V DC-DC controller (Digital smps, be controlled by using one of the texas microcontroller, 20 W), 28V/140V DC-DC controller (TPS40210, texas PWM controller, 90 W). For all of those project I have maked ORCAD simulation, prototype , PCB design by using the CADSTAR , PCB and all experiments in labratory. High speed PCB design: I have experience on high speed PCB design. I have generated CAN controllor card to be used power management. I have known every details about thhe drawing PCB. (thickness of path, critical length of path, direction of trace, location of components, calculation of crosstalk e.t.c Software: C++ , Visual C++, PIC microcontroller coding with C complier, Proteus, MATLAB/SIMULINK, ORCAD, XLINX FPGA programmer and ALTIUM PCB designer. 2 year experience is about: -140V/28V DC-DC 450 W have designed by using ORCAD simulation. -Charge pump circuits, power distribution circuits -Permanent magnet brushless DC motor current control circuits and MATLAB simulation. -Load sharing smps -Digital charge pump circuits -Several analog circuits -Flowchart design FPGA, and written several FPGA codes My freelance works experience: -Switching power supply design or teardown (ELANCE, design non-isolated smps, schematic and PCB) -AFE Design(ELANCE, special designed analog circuit designed according to functionality and cost) -Power Supply (ELANCE, non-isolated smps with PIC controller) -PIC18f97J60 Reading Data from Webpage (ELANCE) -Amplitude Modulated Radio Transmitter (ELANCE) -Therapy Board rework (Analog Design, writing PIC Microcontroller codes and implementation, ELANCE) -Ligthing Surge Arrester (PSCAD Simulation, ELANCE) -Battery aging (FREELANCER) -Magnetic Reader(FREELANCER) -Hardware Design Inkjet and PIC microcontroller coding(QDESK) -Circuit design, pulse width modulator (ELANCE, analog design) -Permanent Magnet Motor Driver(FREELANCER,Schematic, PCB and ATMEGA microprocessor coding) -Uninterruptle Power Supply(Real Life Tech, Schematic, PCB and PIC microcontroller coding) -Wind Energy Simulation(GURU,Modeling Wind Turbine and Power Converter) -Robotics (FREELANCER,Atmega microprocessor coding) -Small magnetic reader (FREELANCER,Without decoder application, PIC18F coding and PCB board) -Reverse Engineer(ELANCE) -Magnetic Reader Interface (FREELANCER) -DC-DC Converter with PIC(FREELANCER) -Program Computer(ELANCE) -Motor driver design(ELANCE) -Design of Eletrical Equipment for Food Truck 2(ELANCE) -Digital Audio PCB Design(FREELANCER) - 07 cbr 600rr gear indicator(FREELANCER) -DC/DC Converter powered from USB port(FREELANCER) -PV Simulation(FREELANCER) -Common Mode choke(GURU) -LED Lighting Product Line Design (GURU) -HYBRID VEHICLE ELECTRONIC MANAGEMENT SYS(GURU) -MIMO OFDM systems (GURU) -Interactive Touch Screen Credit Card (GURU) -Pulse Charing Li-on battery(ELANCE) -High voltage smps(ELANCE) -Automobile power supply(ELANCE) -RF test circuit design(ELANCE) -Camera motor control(QDESK) -EEPROM Programmer(FREELANCER) -High voltage transformer design(FREELANCER) -LDO simulation(FREELANCER) -Digital Motor Controls(PPH) -Sensor design(FREELANCER) Regards.
