“…Literature survey was carried out in eliminating one current sensor out of the two. Recent publications suggested that only one current sensor on grid terminals would be enough to implement FEC by estimating required variables from the available control variables [6].…”

Induction motor (IM) is a workhorse of the industry, whose dynamics can be modified close to that of a separately excited DC machine by field-oriented control technique, which is commonly known as vector control of induction machine. This paper presents a complete performance of the field-oriented control of IM drive in all four quadrants with a single-current-sensor-based active front end converter whose work is to regulate DC link voltage, draw pure sinusoidal currents at unity power factor and to facilitate bi-directional power flow between the grid and the drive. The entire system is completely modelled in MATLAB/SIMULINK and the results are discussed in detail. The vector control analogy of the back to back converters is highlighted along with the experimental results of field-oriented control of induction machine using a dsPIC30F6010A digital signal controller.

“…In the past, various attempts have been made to reduce sensors for control of GSC [9][10][11][12][13][14] and inverter-fed AC motor drives [15][16][17][18][19]. The study [9] by Lee and group proposed a control method for a three-phase voltage source PWM rectifier using only a single current sensor in the DC link.…”

“…However, a single DC-link current sensor is used for reconstructing AC currents in these schemes. Recently, AC side single current sensor-based vector control of front end converter under the balanced grid condition was presented with simulation results in [14]. The control of inverter-fed drives using reduced current sensors as well as the only DC-link current sensor is presented using various methods in [15][16][17][18][19].…”

Conventionally, two AC side current sensors are needed in vector control of grid side converter for AC-DC bidirectional power conversion. The present paper proposes a technique where the control can be achieved with the use of only one AC side current sensor. The control principle utilises the information of unsensed second current sensor for its estimation, which is embedded and readily available in conventional control technique itself. In the proposed method, the grid side d-q axis reference currents of the current controllers are used for estimation of b-axis component of grid current, while the a-axis component of grid current is calculated by one AC side current sensor. Effect of voltage unbalance on the control is also studied in this paper. The proposed control is validated with detailed simulation and experimental observations for both steady-state and transient conditions. The proposed control gives satisfactory performance.
