Dynamic Voltage Adjustment for Intermittent Power Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply systems for feeder devices in board work machines experience significant electric power loss and temperature increases due to the difference in operating voltages between motor and control sections, leading to inefficiencies and potential static electricity issues, which existing technologies fail to adequately address, especially when using contactless power supply methods.
Innovation Solution
An electric power supply device with a regulator section on the receiver side and a supply voltage adjusting section on the supply side, controlled by a supply side control section that matches the received voltage to the drive voltage during operation periods and lowers it during non-operation periods, optimizing power usage and reducing losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric power is always supplied to the motor and control section, then the device can operate reliably, but electric power loss increases and efficiency drops
Solution Approach 1:
The power supply system dynamically adjusts the received voltage based on operational status. During mechanism operation, the supply voltage is set to match the drive voltage for full power delivery. During idle periods, the supply voltage is reduced to approximately match the control voltage, minimizing power loss while maintaining control section functionality
Solution Approach 2:
The system changes the voltage parameter of the power supply based on operational conditions. By switching between high voltage (during operation) and low voltage (during idle periods), the system optimizes the balance between reliability and energy efficiency without requiring separate power supplies
2Power
If high voltage is continuously supplied to the receiver side device, then the mechanism section can operate, but temperature increases due to heat caused by electric power loss
Solution Approach 1:
The system implements periodic voltage adjustment corresponding to the intermittent operation of the mechanism. High voltage is supplied only during actual operation periods when the mechanism needs power, while voltage is reduced during idle periods, creating a periodic pattern that matches the operational cycle and reduces cumulative heat generation
3Loss of energy
If the received voltage is lowered to reduce power loss, then efficiency improves, but the mechanism section cannot operate properly
Solution Approach 1:
The system dynamically switches between two voltage levels based on operational requirements. During mechanism operation, full drive voltage is supplied to ensure proper motor function. During idle periods, voltage is reduced to minimize power loss. This dynamic switching ensures that the mechanism receives adequate power when needed while minimizing energy waste when not in use
