چکیده
The production of large-scale photovoltaics (PVs) is becoming increasingly popular in the field power generation; they require construction plants several hundred megawatts. Nevertheless, these PV with conventional low-voltage (LV) conversion systems not an appropriate technological path. Particularly, large cross-section cables, a high quantity semiconductors, and bulky layout 50/60-Hz step-up transformers make system less competitive terms energy efficiency cost. To overcome drawbacks, this paper introduces new plant topologies intermediate medium-voltage direct current (MVDC) collector that requires galvanic isolation for connecting arrays. Then, design electronic transformer (PET) proposed, implementing 1.7-kV 3.3-kV silicium carbide (SiC) modules. study confirms converter allows use medium-frequency (MF) densities while maintaining efficiency, which facilitates implementation isolated (MV) utility-scale plants.

A novel power converter for photovoltaic applications
A simple and economical power conditioner to convert the power available from solar panels into 60 Hz ac voltage is described. The raw dc voltage from the solar panels is converted to a regulated dc voltage using a boost converter and a large capacitor and the dc output is then converted to 60 Hz ac using a bridge inverter. The ratio between the load current and the short-circuit current of a P...
