Analysis, design, and implementation of an improved gate driver forhigh switching frequency EV application

Abstract

Electric vehicle (EV) battery chargers operate from moderate switching frequency (MSF) to high switching frequency (HSF) to achieve high power density. To operate the HSF power electronic devices, the selection of gate drivers and its associated components is crucial. Laboratory developed gate driver circuits (GDCs) often fail to drive these HSF devices adequately due to noise vulnerability, PWM duty loss and common-mode currents. Further, at MSF and HSF ranges, the gateto-source terminals of the device are subjected to high voltages due to unwanted noise resulting in false turn-on of the switch leading to the converter failure. In this paper, firstly, an improved GDC and it's associated component selection criteria are proposed for HSF EV application. The proposed GDC is simple in structure with minor components; thus, it is cost-effective and highly reliable. Secondly, the proposed GDC is compared with the other commercially available competent GDCs. Power losses, cost and dynamic switching performance are the figures-of-merit for the quantitative assessment. From the comparison, it will be shown that the proposed GDC exhibits an overall superior performance among the popular GDCs. Finally, the distinctive features of the proposed GDC are experimentally validated for several test cases and the obtained results are presented.

“…In addition, the low cost and simple circuit made this gate driver a good choice for efficient GDC designs. The use of the TC4424EPA gate driver was also explained in previous research [2] that is suitable for use in inverters that operate at high frequencies. So that, this type of gate driver is popular for use in SiC, Power IGBT/MOSFET devices that operate over a wide frequency range.…”

“…Awareness of environmental issues, including the depletion of natural resources, increasing levels of pollution, significant greenhouse gas emissions, and rising global temperatures, are important motivating factor for considering electric vehicles (EVs) as a viable solution [1][2][3]. On the other hand, various research efforts contributed to technological advances related to the development of EVs used for mobility activities.…”

“…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.…”

“…Awareness of environmental issues, including the depletion of natural resources, increasing levels of pollution, significant greenhouse gas emissions, and rising global temperatures, is an important factor promoting the use of electric vehicles (EVs) as a viable solution [1][2][3]. The motor controller is a fundamental control component of EVs, has significant effects on the efficiency of the drive system, and is related to the comfort design of EVs [4][5][6]. Hence, it is meaningful to investigate the motor controller in EV applications.…”
