Hybrid controlling and driving circuit and method thereof
First Claim
1. 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;
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; and
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.

Abstract
Methods, circuits, apparatus, and systems related to a hybrid driving and controlling circuit are disclosed. In one embodiment, a hybrid driving and controlling circuit in a double power supply system includes first and second power supplies and at least one load, and the circuit can include: (i) a controller coupled to a hybrid switcher that enables energy transfer from the first and second power supplies; (ii) when a determined energy of the first power supply is sufficient, the controller can control the hybrid switcher to transfer energy from the first power supply to the second power supply; and (iii) when the determined energy of the first power supply is insufficient, the controller can control the hybrid switcher to transfer energy from the second power supply to the at least one load.

8. A hybrid driving and controlling method for a double power supply system that comprises first and second power supplies, at least one load, and a controller, the method comprising:
-
a) sensing, by said controller, status information for said first power supply and said second power supply, wherein said status information comprises an indication of energy stored in said first power supply; b) controlling, by a hybrid switcher, said first power supply to transfer energy to said second power supply if said stored energy in said first power supply is determined to be sufficient; and c) controlling, by said hybrid switcher, said second power supply to transfer energy to said at least one load if said stored energy in said first power supply is determined to be insufficient. - View Dependent Claims (9, 10, 11)
