Solar energy systems

As the "heart" of solar energy systems, PV inverters implement several functions including power control, MPPT regulation, and LVRT protection. A stable and reliable solar inverter ensures normal operation of a power station. As the core component of the PV inverter, the power device is essential for the proper operation of the entire system. Therefore, the selection of an appropriate driver is crucial for an inverter. Bronze Technologies has designed a variety of driver solutions for applications at different power levels.

String Solar Inverters

A stringr inverter adopts a DC/DC+DC/AC two-stage control by managing multiple MPPT inputs separately. The system voltage can range from 1000V to 1500V, and the power can reach up to 325kW. To enhance system performance, a string inverter usually adopts the I-type 3-level architecture, and uses medium-voltage, medium-current, plug-in packaged modules or single switches. Limited by the power density, string inverters generally have relatively strict requirements on component size.
