In the solar power conversion system (Figure 1), the isolated gate drivers and isolated voltage and current-feedback circuits both need to support reinforced isolation. Basic isolation is suficient if another basic isolation is inserted through the isolated data links.
A combination of intrinsic isolation strength, superior mold compound and availability of wide-package options enables TI devices to address the requirements of solar inverter designs with rated system voltage up to 1000 V RMS and a rated DC link voltage of up to 1500 VDC.
A solar photovoltaic (PV) inverter converts electrical power from a solar panel and deploys it to the utility grid efficiently. DC power from the solar panels, which act like a dc current source, is converted to ac and fed onto the utility's grid in the correct phase relationship—with up to 98% efficiency.
Almost any solar systems of any scale include an inverter of some type to allow the power to be used on site for AC-powered appliances or on the grid. Different types of inverters are shown in Figure 11.1 as examples. The available inverter models are now very efficient (over 95% power conversion efficiency), reliable, and economical.
PV panels convert sunlight into dc voltage, which must be converted to high-voltage ac to minimize line losses and enable longer power transmission distances. The PV solar inverter performs this dc-to-ac

Isolation is required within solar PV inverter systems, primarily because of the high voltages appearing on an ac grid. The ac voltage, even in single-phase systems, can peak at 380 V.
