1Speed
If existing buck-boost structure is used, then the circuit can regulate output voltage, but the voltage stabilization time is too long when switching from bucking mode to boosting mode
Solution Approach 1:
The patent divides the voltage regulation process into distinct phases by introducing a fifth switch that can independently control the input power supply connection. This segmentation allows the circuit to bypass intermediate switching states, enabling direct transition between bucking and boosting modes, thereby significantly reducing voltage stabilization time.
Solution Approach 2:
The fifth switch is pre-configured to directly connect the input power supply to the appropriate circuit path based on the required operating mode. By preparing the power supply connection in advance and enabling direct switching between modes, the circuit eliminates delays associated with sequential switching operations, achieving faster voltage regulation response.
2Use of energy by moving object
If existing buck-boost structure is used, then the circuit can reduce system power consumption, but the communication reliability deteriorates due to prolonged voltage stabilization time
Solution Approach 1:
By segmenting the power supply control function with the fifth switch, the circuit achieves faster mode transitions that maintain energy efficiency while eliminating communication failures caused by prolonged stabilization periods, thus preserving both low power consumption and high communication reliability.
Solution Approach 2:
The pre-configured fifth switch enables immediate power supply connection changes when mode switching is required, ensuring that voltage regulation completes quickly enough to maintain communication reliability without sacrificing the energy-saving benefits of buck-boost operation.
3Ease of operation
If existing buck-boost structure is used, then the circuit can regulate voltage, but the signal sensitivity is reduced due to long voltage stabilization time
Solution Approach 1:
The segmented control architecture with the fifth switch enables rapid voltage mode switching that completes before signal sensitivity is affected, maintaining both ease of voltage regulation and high signal sensitivity by eliminating the prolonged stabilization period.
Solution Approach 2:
By pre-configuring the power supply connection paths and enabling direct switching through the fifth switch, the circuit achieves fast voltage regulation that preserves signal sensitivity, ensuring that voltage changes occur quickly enough to maintain communication system performance.
