SWITCHING REGULATOR CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17937492 titled 'SWITCHING REGULATOR CIRCUIT
Simplified Explanation
The patent application describes a switching regulator that uses one or two inductors to connect an input circuit and a multi-output end circuit. This regulator can drive different loads at different voltage levels.
- The input circuit includes multiple input switches and can operate in different modes (buck, boost, boost-buck) to boost the input voltage or ground voltage and provide an applied voltage to the inductors.
- Each mode is selected based on the target voltage for one of the unit output ends in the multi-output end circuit.
- The output voltages are monitored and the on-times of switches in the multi-output end circuit are controlled to maintain the output voltages within the desired range.
Potential applications of this technology:
- Power supply systems for electronic devices
- Battery charging systems
- Renewable energy systems (solar, wind, etc.)
- Electric vehicle power management
Problems solved by this technology:
- Efficiently driving different loads at different voltage levels
- Maintaining stable output voltages within target ranges
- Reducing the complexity and cost of the switching regulator circuit
Benefits of this technology:
- Improved energy efficiency
- Flexibility in handling different loads and voltage levels
- Simplified circuit design
- Cost savings in manufacturing and operation.
Original Abstract Submitted
Embodiments of a switching regulator include a single inductor or two inductors connecting an input circuit and a multi-output end circuit that may drive different loads at different respective voltage levels. The input circuit may include a plurality of input switches, and may boost an input voltage or a ground voltage via operation in one of a plurality of selected modes such as a buck mode, a boost mode and a boost-buck mode, to thereby provide an applied voltage to the one or more inductors. Each selected mode may be based on a target voltage for one of a plurality of unit output ends (output load driving sections) in the multi-output end circuit. Output voltages may be monitored and on-times of switches controlled in the multi-output end circuit to maintain the output voltages in respective target ranges.
