Photovoltaic (PV) Dry-Type Transformer

Photovoltaic transformers are key equipment in photovoltaic power generation systems, mainly responsible for voltage conversion and electrical isolation. In the process of photovoltaic power generation, it converts the low-voltage direct current generated by photovoltaic modules into alternating current through an inverter, and then boosts it to a voltage level suitable for grid connection.
