Multi-Channel DC-DC Converter Control for Flexible Elevator Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require separate DC-DC converters for each power source and storage device, limiting flexibility and necessitating new converters for upgrades or changes, while existing multi-channel DC-DC converters lack adaptability to different power requirements and configurations.
Innovation Solution
A single multi-channel DC-DC converter system with independently connectable channels and a programmable controller that stores information on connected devices, allowing flexible power management and adaptation to various power sources and storage devices, enabling seamless integration of new or upgraded components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate DC-DC converters are used for each power source and storage device, then each device can be independently controlled, but the system complexity increases and flexibility decreases when upgrades or changes are needed
Solution Approach 1:
The patent combines multiple separate DC-DC converter functions into a single multi-channel DC-DC converter unit. This single converter can connect to multiple power sources and storage devices simultaneously, reducing the total number of converter units needed while maintaining independent control capability through its multi-channel architecture
Solution Approach 2:
The single multi-channel DC-DC converter is designed to serve multiple functions by connecting to different types of devices (power sources and storage devices) through its multiple channels. This universal design allows the same converter unit to handle various device configurations and upgrade scenarios without requiring dedicated converters for each device type
2Power
If existing multi-channel DC-DC converters are used with single device connections, then current drawing capabilities are increased, but adaptability to different power requirements and configurations is limited
Solution Approach 1:
The patent implements dynamic control of the multi-channel DC-DC converter channels, allowing the system to adaptively activate or deactivate specific channels based on real-time power requirements and device configurations. This dynamic operation enables the converter to optimize its power drawing capability while adapting to different operational scenarios and device types
Solution Approach 2:
The converter channels are segmented into independently controllable units, allowing selective activation of specific channels based on the connected devices and power requirements. This segmentation enables flexible configuration where different channels can serve different devices or functions, enhancing adaptability while maintaining high current drawing capability when needed
