Regenerative Battery Charging Control Method for PMSM Drive without a DC/DC Converter

Abstract

This paper illustrates regenerative battery charging control method of the permanent magnet synchronous motor (PMSM) drive without DC/DC converter. Conventional control methods for battery current and voltage control methods generally use a bidirectional DC/DC converter for regenerative control. The reason to use this DC/DC converter is the DC-Link current ripple of the inverter of is affected by switching of the inverter and the motor speed. This problem causes to use a low pass filter (LPF) for sensing the DC-link current, however, it occurs deteriorating the control performance. In this paper, battery current and voltage control methods using only the motor drive are illustrated. To control the DC-link current, power control is performed using the look-up table (LUT) data that are extracted from the experiment. In addition, an applicable method for the variable DC-link voltage of the proposed regenerative control method is illustrated.

Integrated Vehicle-Following Control for Four-Wheel Independent Drive Based on Regenerative Braking System Control Mechanism for Battery Electric Vehicle Conversion Driven by PMSM 30 kW

“…Figure 17 shows the driving distance of the electric vehicle from the simulation using the EUDC driving pattern in a traditional BEV, RBS-only battery, and HESP-RBS. Figure 18 illustrates the upcycling to a commercial-scale experimental arrangement of the RBS program, which includes the HESP, DC/DC chopper [27,28], and a three-phase PMSM. The specifications of these experimental components are provided in Table 5.…”

“…As shown in Figure 20a-c, the engagement of brakes led to a decrease in the back-EMFs, and the RBS control mechanism evenly allocated the braking force to the mechanical brakes of both the front and rear wheels. Figure 18 illustrates the upcycling to a commercial-scale experimental arrangement of the RBS program, which includes the HESP, DC/DC chopper [27,28], and a three-phase PMSM. The specifications of these experimental components are provided in Table 5.…”

Ion Motor as a New Universal Strategy for the Boosting the Performance of Zn-Ion Batteries

“…Generally, batteries are composed of anodes, cathodes, and electrolytes, which achieve the charging and discharging process of batteries. The directional flow of the electrolyte is extremely important because it helps in the diffusion process of ions, eliminating the concentration polarization formed on the electrolyte. − Furthermore, it accelerates the renewal of active materials on the electrode surface and improves the output power and durability of the battery. − In the gravitational field, the ion concentration gradient generated during the charging and discharging process causes serious concentration polarization and dendrite problems, even causing accidents such as the internal short circuit of the battery, − which dramatically reduces the energy efficiency and cycle life of batteries. Among the reported batteries, the existing flow batteries must be equipped with pumps to drive the electrolyte flow during the charging and discharging process. − Furthermore, the existence of mechanical pumps causes the following three problems in the actual application of flow batteries: (1) 1–2 pumps consume 5–10% of energy, which reduce the output energy of the battery.…”

Compensation of Interpolation Error for Look-Up Table-Based PMSM Control Method in Maximum Power Control

“…Owing to these problems, motor control systems that generate current commands in look-up tables use 2D interpolation. 2D-LUT with 2D-interpolation is applied not only for traction motor drives of Hybrid Electric Vehicle(HEV) [2] and Electric Vehicle(EV) [3], actuator driver for automotive systems [4], but also for many other PMSM-based applications [5,6]. Additionally, there exist other table-based methods besides the aforementioned current command method, such as the voltage-vector table [7], current angle table [8], 3D-LUT-based control method [9].…”
