Problem statement: Motor drive design challenge for Solar Pump
Problem Statement
Growing demand for Solar pump drive, but limited availability of Indian designed products
Weak local eco system for design and manufacturing of pump drive platforms, leading to mass import of drives
Technical Requirements:
- PV Input (DC) to (AC) Motor Load – Offline (Refer table for specification)
- Software based MPPT (Power Based)
- Scalable design from 1HP to 10HP ( 1/ 3 / 5 / 7.5 /10 )
- Motor model: Induction or PMSM/BLDC Pump model: Submersible or Surface
- Algorithms: FOC or V/F, FOC will be preferred
- Key protection features: OVP, OCP, OTP, PV reverse protection, short circuit, motor jam protection, phase loss, dry run
- Interface to RMS (Remote Monitoring System) or RMS can be part of design will be added advantage. LCD display to show,
voltage, current, power, fault, flow rate and status, cloud interface through RMS
Requirement
Using Infineon components like power devices (IGBT power modules/ Discretes, MOSFET, IPM, Gate driver IC’s),
Controllers, Sensors, SMPS IC’s and Connectivity chips, wherever applicable.
