POWER SUPPLY DEVICE AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17825825 titled 'POWER SUPPLY DEVICE AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a DC-DC converter that has two converters and a mode selector. The first converter generates a power voltage using two driving methods: a normal mode and a power saving mode. The second converter also generates a power voltage using two driving methods, with the number of turn-on times being less in the power saving mode. The second converter also determines different magnitudes of the power voltage in the power saving mode and the normal mode. The mode selector controls the converters based on the selected mode.
- The DC-DC converter has two converters and a mode selector.
- The first converter generates a power voltage using a normal mode and a power saving mode.
- The second converter generates a power voltage using a driving method with fewer turn-on times in the power saving mode.
- The second converter determines different magnitudes of the power voltage in the power saving mode and the normal mode.
- The mode selector controls the converters based on the selected mode.
Potential Applications
- Power management systems in electronic devices
- Renewable energy systems
- Electric vehicle charging systems
Problems Solved
- Efficient power conversion in different driving modes
- Reduction of power consumption in power saving mode
- Flexibility in controlling power voltage magnitudes
Benefits
- Improved energy efficiency
- Extended battery life in power saving mode
- Customizable power voltage levels for different modes
Original Abstract Submitted
A DC-DC converter includes a first converter outputting a first power voltage in a first driving method of generating an inductor current by alternately turning on transistors in a normal mode and outputting the first power voltage in a second driving method of generating the inductor current with the number of turn-on times less than that of the first driving method in a power saving mode, a second converter outputting a second power voltage in a third driving method of generating the inductor current with the number of turn-on times less than that of the second driving method in the power saving mode and determining differently magnitudes of the second power voltage in the power saving mode and the second power voltage in the normal mode, and a mode selector supplying a mode control signal to the converters to drive the converters according to one of the modes.
