This article elaborates on a reduced switch count-based inverter for a single-stage solar photovoltaic (SPV) fed induction motor (IM) with sensorless speed control for water pumping applications. The traditional SPV-fed IM for water pumping applications requires a six-switch voltage source inverter (SSVSI) for transforming the DC power from the SPV system into AC power. However, the same performance is achieved using a four-switch voltage source inverter (FSVSI). Here, the entire system requires less number of switches and hence reduces switching losses and cost as compared to the traditional solar water pumping system. Moreover, the sensorless speed control is implemented using a speed estimator to reduce the overall cost further and enhance reliability. The reference voltage ( V d c r ) is achieved using an adapted incremental conductance (AINC), and the control of IM is performed using direct vector control (DVC). The control signals for the proposed system are generated using DSPACE DS-1104 for real-time implementation. The proposed SPV-fed FSVSI-based 1-HP IM operation is performed at different irradiation levels in the MATLAB-Simulink environment and validated experimentally.

Summary This article discloses a clamping sequence duty ratio control (CSEQ‐DRC) for photovoltaic (PV)‐fed indirect vector control (IVC) of induction motor (IM) drive. Solar PV is one of the prominent renewable green energy resources and made a pollution‐free power generation without carbon emission. The PV‐fed IM drives are used in many applications such as water pumping, electric vehicle, industrial applications, etc. However, solar panels suffer from low efficiency. Moreover, it can be overcome using the maximum power point tracking (MPPT) technique, and the MPPT is achieved using incremental conductance (Inc‐Cond). The speed of IM can be controlled using IVC with the help of an inverter. The inverter is inherently controlled based on the pulse width modulation (PWM) techniques for reducing the voltage or current harmonics. Here, the proposed CSEQ‐DRC involves two switching sequences such as CSEQ0 and CSEQ1, in every sector region. For every sector region, the appropriate sequence can be operated/selected in the less area of root mean square (RMS) of the stator flux ripples (SFRs) to reduce the line voltage/current profiles of the IM. Consequently, the torque ripples and speed fluctuations are further reduced significantly with the proposed CSEQ‐DRC than the conventional space vector duty ratio control (CSVDRC). In real‐time applications of PV‐fed IVC IM, the interface of the DSPACE DS‐1104 controller is used here to implement for both the proposed CSEQ‐DRC and CSVDRC techniques. Also, the overall performance of the IM drive is improved with the proposed technique as compared to the CSVDRC at different operating conditions.
