Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital power distribution systems face challenges in ensuring equal load sharing among parallel power-limited circuits, synchronizing startup, and prioritizing power delivery to critical loads, particularly in scenarios where minor variances in circuit impedance and lack of synchronization lead to over-power conditions and indefinite faulty start-up sequences.
Innovation Solution
A digital power receiver system with a control circuit that monitors internal voltages and limits power output until a predetermined value is reached, allowing synchronized operation and prioritization of power delivery across multiple loads, utilizing the Packet Energy Transfer (PET) protocol to optimize safety, efficiency, resiliency, control, and routing, and enabling configurable priority schemes through an Application Programming Interface (API).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple parallel receiver circuits are used to distribute digital power, then power delivery capacity is improved, but load sharing equality deteriorates due to impedance variances
Solution Approach 1:
The control circuit monitors the voltage level on each transmission line pair and uses this feedback to dynamically adjust the power output of individual receiver circuits. This closed-loop control ensures that each receiver contributes equally to the total power delivery, compensating for impedance variations and achieving equal load sharing across all parallel circuits.
Solution Approach 2:
The system dynamically changes the power output parameter of each receiver circuit based on real-time voltage monitoring. By adjusting the power delivery parameter of individual receivers, the system achieves balanced load distribution across parallel circuits with different impedance characteristics, resolving the contradiction between increased power capacity and equal load sharing.
2Reliability
If power transmission lines are isolated for voltage analysis, then fault detection capability is improved, but power transfer continuity deteriorates
Solution Approach 1:
The system implements periodic isolation of power transmission lines at controlled intervals to perform voltage analysis and fault detection. This periodic action allows the control circuit to monitor system health without continuous disruption, maintaining power transfer continuity during normal operation while enabling regular safety checks. The brief isolation periods are scheduled to minimize impact on overall power delivery continuity.
3Stability of the object's composition
If receiver circuits start up simultaneously, then system synchronization is improved, but over-power conditions occur due to impedance variances
Solution Approach 1:
The system transitions from static simultaneous startup to dynamic sequential startup with staggered timing. Each receiver circuit is enabled at different time intervals, allowing the control circuit to monitor voltage levels and adjust power output dynamically. This dynamic approach maintains system synchronization while preventing over-power conditions by ensuring each receiver gradually contributes to the total load based on real-time system state.
4Object-affected harmful factors
If power output is limited to ensure safety, then personnel safety is improved, but minimum power availability deteriorates
Solution Approach 1:
The system implements partial power limitation where individual receiver circuits operate below their maximum capacity during startup and transient conditions, but can deliver full power when system conditions permit. The control circuit accumulates energy in capacitive elements during limited-power operation and releases it when voltage thresholds are met, ensuring both safety during critical periods and adequate power availability when conditions allow.

AI summary
Digital power is regulated by transmitting digital power via a transmission line pair to at least one receiver circuit in a digital power receiving system. The digital power is converted into analog power in the receiver circuit. The analog power is transmitted to at least one power conditioning circuit, and output power is transmitted from the power conditioning circuit. At least one voltage in the digital power receiver system is monitored; and, in response to that monitoring, the output power from the power conditioning circuit is regulated to improve at least one of safety, efficiency, resiliency, control, and routing of power.
