----------------------------------------------------------------------***--------------------------------------------------------------------Abstract— This paper presents the design and development of a resolver-based Permanent Magnet Synchronous Motor (PMSM) controller for electric vehicle applications. Nowadays, internal combustion (IC) engines are increasingly being replaced by plug-in hybrid, hybrid, or electric vehicles due to their disadvantages. In electric vehicles, the system comprises various components, including the Motor Control Unit (MCU), Intelligent Vehicle Control Unit (iVCU), Battery Management System (BMS), Fault Diagnostics Unit, and PMSM. This paper focuses primarily on the Motor Control Unit, which includes the control board, gate driver board, capacitor bank, and power board. Resolvers and encoders are utilized to measure the speed, position, and direction of the motor shaft. This feedback is used to adjust the power delivered to the motor, ensuring desired operating characteristics. Resolvers are preferred over encoders for harsh environments with high temperatures or radiation. A microcontroller generates PWM pulses to drive the inverter circuit and operate the PMSM motor. Keywords—PPMS motor, fly back converter, LT spice, op-amp, PMIC IC.
I. INTRODUCTION Electric vehicles (EVs) were first invented in the early 19th century, around the 1820s and 1830s. They became economically viable in the 1890s. Despite their potential, EVs were initially less popular due to higher costs, lower speed ranges, and shorter distances compared to internal combustion engines (ICEs), which dominated the 20th century [1]. By the early 21st century, interest shifted towards EVs due to the environmental impact of ICEs, including carbon emissions, climate change, environmental damage, and adverse effects on human health [2]. © 2024, IRJET

Since 2010, global sales of electric vehicles have surged, reaching one million by September 2016. By the end of 2019, there were 4.8 million EVs in use, and it was projected that 10 million EVs would be sold by the end of 2020. This growth reflects the evolution of electric vehicles [3]-[6]. Compared to other motor types such as DC motors, synchronous motors, and induction motors, Permanent Magnet Synchronous Motors (PMSMs) offer superior performance, including better dynamic and steady-state characteristics, higher efficiency, reduced size, increased torque, and higher power density. These advantages lead to smaller motor sizes and fewer torque ripples during commutation [7]-[10]. PMSMs are widely used in defense, agriculture, and everyday applications due to the rapid development of power electronics. PMSMs can be controlled using two primary methods: vector control and direct torque control. Vector control involves managing and measuring the stator current vector to control motor torque by generating excitation and torque currents based on the field-oriented principle [8]-[12]. Direct torque control directly regulates the torque [13]. In alternating current machines, such as induction or AC motors, torque creation is similar to that of direct current motors. The stator generates fields, and the rotor is not perpendicular. Field-Oriented Control (FOC) decouples flux and torque components, offering several advantages over the V/F control approach [14]-[18]: 1. 2. 3. 4. 5.
Provides full torque across a wide range of speeds. Improved dynamic performance. Effective transient and steady-state analysis. High torque and low current during starting. Enhanced efficiency.
