Design and development of quasi‐resonant switched step‐up converter for solar energy‐based brush‐less DC motor drive.

Summary: The air‐conditioning sector experiences sustainable growth in recent time and resulted in hike in energy demands. To preserve the environment, reduce energy consumption, and improve social‐economic developments, these air‐conditioning loads should be either curtailed or driven using the green energy. In this work, the design, development, and control of quasi‐resonant switched step up converter (QRSSUC) are presented for solar energy‐based brushless DC motor (BLDCM) drive coupled with air‐conditioning loads. The QRSSUC is placed in between solar photovoltaic supply (SPVS) and DC link of a voltage source inverter. It reduces the switching losses by using zero voltage switching across the switch. The proposed system advises a promising option for solar energy‐based solution for air‐conditioning loads. The proposed position sensor less BLDCM drive is cost effective and more reliable as mechanical sensors are completely eliminated from the control. The MATLAB R2019 and dSPACE 1104 controller board are used to obtain simulation and experimental results. Test results are obtained on a developed prototype to verify that the proposed system can operate under the wide range of solar irradiations. [ABSTRACT FROM AUTHOR]
