Pump electronic circuit for coupling power supply and solar module for drive of low-voltage submerged pump, has pump motor operated with solar current, where regulation of circuit takes place via co-action of capacitors and resistors

摘要

The pump electronic circuit (13) has a pump motor (14) operated with solar current. The regulation of the pump electronic circuit takes place via co-action of two capacitors (16, 17), Schottky diode (18), two resistors (19, 20), adjustable resistor (21) and a voltage controller (22). The power of a solar assembly of a solar module (12) corresponds to the power of the pump motor during optimal solar radiation.
