摘要: A new high voltage gain dc-dc converter is proposed on this work as a viable solution to step-up low battery into dc link. This suitable for non-isolated on-line UPS systems with common neutral connection, that improves bypass circuit installation. Furthermore, smaller size, higher efficiency, and increased reliability are features spread the transformerless products. The adopted control strategy uses hybrid implements both analog digital controllers, average current mode control. It presents characteristic of continuous input through batteries improve its lifetime, maximum across controlled switches equal one fourth total output voltage, equalization dc-link capacitors intrinsic. In order verify feasibility topology, principle operation, theoretical analysis, experimental waveforms shown 1.55 kW assembled prototype.
