Abstract
A solar power supply system includes at least one solar power conversion circuit and an inverter circuit. Each solar power conversion circuit comprises a solar module and a direct current (DC) module. The solar module converts the solar power into the DC signals. The DC module with two-stage conversion comprises a DC transformer circuit and a maximum power point tracking circuit, to boost the DC signals and adjust output power of the solar module to a maximum value. The inverter circuit converts the boosted DC signals output from the solar power conversion circuits into AC signals and combines the AC signals into the AC utility network.
