  • Discontinuous conduction current mode maximum power limitation photovoltaic converter
    Patent number: 8653804
    Abstract: A discontinuous conduction current mode maximum power limitation photovoltaic converter connects to a ground and a solar cell having a temperature compensation signal and an output power and being solarized and includes a direct current/direct current voltage converter and a maximum power control circuit. The direct current/direct current voltage converter connects to the solar cell, includes an input terminal and an output terminal, offers a stable voltage and has an output voltage signal and an inner current. The maximum power control circuit connects to the direct current/direct current voltage converter and the solar cell, controls the direct current/direct current voltage converter to limit the output power of the solar cell to maximum and includes a temperature compensation feedback circuit, an output voltage feedback circuit, a current detection circuit and a main control circuit.
