Reliable motor control is important for electric vehicle applications. The control process requires accurate measurements of the current and rotor position information to establish correct motor control design, particularly in sensorless permanent magnet synchronous motor control systems. Practical issues regarding the motor control circuit, such as the effects of parasitic element behavior on the switching components in the insulated gate bipolar transistor-driven inverter, were discussed in this study. It analyzed the effects of parasitic elements that can cause the ringing of switching losses and affect the spike of the signal in the motor current, which must be avoided in the implementation of motor control. The gate driver circuit topology was improved to reduce this effect in motor control devices. The proposed gate driver circuit design with the ringing suppression circuit configuration achieved good performance by keeping the signal spike at less than 10% in the motor current. Furthermore, a signal spike or noise was not observed in the estimation results of rotor position when using current information as the parameter control process. Both conditions were verified by experiments on the designed motor control devices. Under these conditions, signal precision can be achieved in motor control.

MOSFETs are used in electronic circuits because they have high switching efficiency. Typically, MOSFETs are wired in parallel for applications that require high power. Theoretically, this circuit can multiply the current capability of parallel MOSFETs. However, even if all the MOSFETs in a parallel circuit have the same serial number and manufacturer, they might not necessarily have the same current characteristics. This could lead to issues with current imbalances, potentially causing harm to the MOSFETs, especially under severe circumstances. This study introduces a new Active Gate Driver (AGD) technique to balance the current in a parallel MOSFET circuit. The current difference can be used to modulate each MOSFET duty cycle. Specifically, the MOSFET with the smallest current capacity is configured as the Master, while the MOSFET following it is designated as the Slave. The interrupt time value for the duty cycle of each Slave MOSFET is influenced by the current differential between the Master and Slave. Consequently, different duty cycles for the Master and Slave MOSFETs can maintain the same current level. Based on the results of experiments conducted on three MOSFETs, it is evident that the AGD approach can effectively balance the current to an optimum level.

“…Control of the electric motor in the EVs drive system is a crucial role to achieve its optimal performance [4]. Therefore, the overall design of the control system must be able to operate reliably, including the control method and motor control devices used [1,2,5]. The motor control method without speed or position sensors (sensorless motor control) is one of the attention of researchers to implement the method in EVs motor control systems [6].…”

“…Switching losses in the power inverter cannot be avoided because the behavior of the semiconductor component itself causes ripples or noise when transitioning from ON to OFF, which is usually called a ringing switching condition [17]. Many researchers have conducted a lot of research on gate driver circuit designs that are implemented in motor control system devices [2,3,5,[16][17][18][19]. However, the study of the effect of ringing switching behavior on the application of sensorless motor control systems is still unknown.…”

“…Therefore, the proposed GDC is designed comprehensively by considering the effect of ringing switching on the power inverter components and providing a good isolation system in the implementation of sensorless control motor devices in this study. The addition of a capacitance filter, resistor bootstrap and snubber circuit has proven to overcome the problem of noise and switching losses in a circuit board design [5,16,18]. However, selecting the best circuit is an important thing to pay attention to effective sensorless motor control devices designed.…”

Reliable motor control design is a critical part of the electric vehicle application. Control techniques and motor control devices play an important role in achieving system reliability. In this study, motor control devices have been proposed to implement control techniques in sensorless PMSM. Motor control devices including PWM signal generation by FPGA, gate driver circuit (GDC), and power inverter were developed to be integrated into single-stage motor control devices for sensorless motor control applications. Improvements in GDC design have been the focus to increase the performance of the motor control devices used. Switching losses due to the parasitic elements caused ringing switching behavior of the power inverter circuit, which reduces the performance when the system is integrated. Moreover, in the implementation of sensorless motor control using observer techniques, these conditions affect the accuracy of rotor position estimation, which uses the current or voltage information of the power converter as a variable in the observer design model. Therefore, a GDC design using IR2110 with additional ringing suppression circuit configuration was proposed for the application of motor device control topology to improve the performance of sensorless motor control system. Furthermore, the reduction of switching losses, reduction of current distortion, and accuracy of rotor position information were confirmed by experimental results.
