Comments Off on Delta Power Control Strategy for Multi-String Grid-Connected PV Inverters
Posted in: IEEE 2017, Power System
Delta Power Control Strategy for Multi-String Grid-Connected PV Inverters Abstract: With a still increasing penetration level of grid-connected PV systems, more advanced active power control functionalities have been introduced in certain grid regulations. A delta power constraint, where a portion of the active power from the PV panels is reserved during operation, is required for […]

Comments Off on An Improved Zero-Current-Switching Single-Phase Transformerless PV H6 Inverter with Switching Loss-Free
Posted in: IEEE 2017, Power System
An Improved Zero-Current-Switching Single-Phase Transformerless PV H6 Inverter with Switching Loss-Free Abstract: In this paper, a switching loss-free (SLF) concept for the first six-switches H-bridge inverter (H6-I) topology is proposed. SLF means that its switches are able to operate with soft turn-on and turn-off transitions. In order to implement the SLF goal, a new resonance-trajectory […]
