Patent ID: 8868249

Claim:
A hybrid driving and controlling circuit in a double power supply system having first and second power supplies and at least one load, the circuit comprising: a) a controller coupled to a hybrid switcher that enables energy transfer from said first and second power supplies, wherein said first and second power supplies are connected at a common node, wherein said first power supply comprises a solar panel configured to convert natural light into electrical energy, and wherein said second power supply comprises a battery configured to store energy; b) when a determined energy of said first power supply is sufficient, said controller being configured to control said hybrid switcher to transfer energy from said first power supply to said second power supply; c) when said determined energy of said first power supply is insufficient, said controller being configured to control said hybrid switcher to transfer energy from said second power supply to said at least one load; d) a first inductive component connected to a first power switch and said second power supply; and e) a second inductive component connected to said first power switch, said first inductive component, and an output diode, wherein said at least one load is connected to said output diode and said common node.
