42 Design, Simulation and Construction of Two Synchronized DC Motors' Driver for EVs
Download citation file:
Electric vehicles (EVs) are simplest way to replace fossil fuel powered vehicles. EVs are relatively cheap, have little environmental impact and are relatively matured technology. Using an electronic control board and two power boards, a high power EV drive system was designed and constructed (for the vehicles up to 100 kW). The controller uses power IGBT module and microcontroller technology to simultaneously control two DC series motors. The driver controls direction of motion and causes differential speeds of motors relative to steering rod and acceleration pedal position. Driver simulation in MATLAB proved that the required conditions were satisfied by PID...
