A Novel Power Supply to Drive Electrodynamic Screens for Use by Water-Free Self-Cleaning Solar Panels

A novel power supply design for optimized electrodynamic screen (EDS) activation to be used for water-free cleaning of solar panels using is described. The power supply consists of three distinct cascaded boost converters and a high voltage switching network for capacitive loads, which are capable of producing three-phase 1.3kV square waves from 12V input. These high voltage square waves drive the EDS that remove dust from the solar panels via Coulomb forces. The supply self-regulates its peak output voltage, and is easily adjustable for different EDS applications. The unit is more reliable, cost-effective, and consumes less power than comparable units.
