Photovoltaic water pumping based on open-ended winding induction
Indian scientists have designed a water-pump drive system that is powered exclusively by photovoltaics. The proposed system configuration reportedly ensures effective use of both the solar modules and the motor.
ABB Motion launches new solar drive for water pumping
ABB Motion has unveiled a new solar drive for water pumping, featuring integrated maximum power point tracking (MPPT) logic to maximize operations, with an input voltage ranging from 225 V to 800 V.
New model estimates PV potential for water pumping in Africa
An international team has developed a numerical model that calculates how much groundwater can be pumped by PV systems of different sizes across the entire African continent. The results show that larger PV systems do not always pump the highest volume of water.
Novel photovoltaic water pump from Spain
A Spanish startup has developed a new pumping system that can operate in DC and AC modes. It can work for direct irrigation and with a water tank.
A multi-level inverter for solar water pumps
Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.
