Solution Overview
Problem
Existing power electronics technologies face challenges in integrating air-cooling solutions for high-power systems, as they are designed to handle AC to DC, photovoltaic DC, and energy storage DC separately, making it difficult to combine them effectively.
Innovation Solution
The proposed solution involves designing photovoltaic and energy storage interfaces as universal interfaces that can be accessed by both photovoltaic systems and energy storage systems, with a control method that adjusts the internal circuit of the optical storage converter based on the type of system accessed, using voltage and current measurements to determine the appropriate operation mode for the DC to DC converter circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate interfaces are designed for AC to DC, photovoltaic DC, and energy storage DC, then each interface can be optimized for its specific function, but the device complexity increases and integration becomes difficult
Solution Approach 1:
The patent applies universality by designing a single universal interface that can handle AC to DC, photovoltaic DC, and energy storage DC conversions. The converter uses a unified hardware architecture with a DC to DC converter circuit that can operate in different modes (boost, buck, buck-boost) depending on the connected load type, eliminating the need for separate dedicated interfaces for each conversion type.
Solution Approach 2:
The patent applies dynamics by implementing dynamic circuit mode switching based on real-time detection of the connected load type. The control device dynamically adjusts the DC to DC converter circuit between boost mode, buck mode, and buck-boost mode according to whether the connected device is a photovoltaic system, energy storage system, or AC to DC converter, allowing a single interface to adapt to multiple functions.
2Device complexity
If a universal interface is designed to handle multiple conversion types, then device complexity is reduced and integration is easier, but the ability to optimize each interface for its specific function is compromised
Solution Approach 1:
The control device dynamically detects the type of connected load and switches the DC to DC converter circuit between different operating modes (boost, buck, buck-boost) to optimize performance for each specific conversion type while using a single universal interface hardware architecture.
Solution Approach 2:
The patent changes operational parameters (circuit configuration, switching modes, control algorithms) based on the detected load type. The same physical interface hardware is reconfigured through parameter changes to provide optimized performance for AC to DC, photovoltaic DC, and energy storage DC conversions.
3Ease of manufacture
If separate photovoltaic and energy storage interfaces are designed, then each interface can be customized for its specific requirements, but material costs increase and flexibility decreases
Solution Approach 1:
The patent uses a single universal interface design that serves multiple purposes (AC to DC, photovoltaic DC, energy storage DC conversions), eliminating the need to manufacture separate dedicated interfaces for each conversion type, thereby reducing material costs while maintaining customization through software/control logic.
Solution Approach 2:
The universal interface dynamically adapts its configuration and operating parameters based on the connected device type, providing customized optimization for each conversion scenario without requiring separate physical interfaces, thus reducing material usage while maintaining ease of manufacture.
