Abstract
A high-power boost converter including two or more inductors coupled to an input DC power source and to switches that can be modulated to control the output power of the high-power boost converter. The two or more inductors are further coupled to each other electrically, magnetically, or both electrically and magnetically.
Claims20
A photovoltaic (PV) power system providing electrical power at an output voltage and comprising:
- a first inductor electrically connected to the output of at least one PV source;
- a second inductor electrically connected to the output of the at least one PV source, and electrically coupled to the first inductor;
- a first electrical switch electrically connected to both the first inductor and an output of the PV power system;
- and,
- a second electrical switch electrically connected to both the second inductor and the output of the PV power system,
- wherein both the first and second electrical switches are repeatedly modulated to control the output voltage.
