Multi-winding transformers specifically built to step up solar central inverter output while suppressing high frequency harmonics and DC offsets.
Utility scale solar PV plants generate power via solar inverters that output pulsed pulse-width modulated (PWM) AC voltages with significant harmonic content.
Indian Power Trans inverter duty transformers feature multiple separate low-voltage windings to connect multiple inverters to a single transformer unit, complete with electrostatic shielding between HV and LV windings.
