Solution Overview
Problem
Current power supply systems for datacenters lack flexibility in voltage combinations, system architecture adaptation, and safety during maintenance, as they fail to effectively isolate high and low voltages, leading to inefficiencies and safety risks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-phase power supply modules are connected in series and all modules are placed in one box without isolation structure, then the system structure is simple, but it cannot guarantee safety during live maintenance and cannot flexibly correspond to different input and output voltages
Solution Approach 1:
The power supply system is divided into multiple independent power supply modules, each with its own high-voltage chamber and low-voltage chamber. These modules can be independently installed, maintained, and isolated from each other, enabling safe live maintenance while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
An insulating partition is introduced as an intermediary structure between the high-voltage chamber and low-voltage chamber. This partition provides electrical isolation and safety protection during live maintenance, while being a simple additive component that does not significantly increase overall system complexity.
2Adaptability or versatility
If a modular structure with isolation units is implemented to achieve flexible voltage combinations and safety isolation, then adaptability and safety are improved, but the number of components and system complexity increase
Solution Approach 1:
Each power supply module is designed as a universal unit that can handle different voltage combinations. The modules use standardized high-voltage cavities, low-voltage cavities, and isolation units that can be configured for various input and output voltage requirements, reducing the need for specialized components for each voltage scenario.
Solution Approach 2:
The system allows dynamic configuration of power supply modules to adapt to different voltage requirements. Modules can be selectively connected in series or parallel, and the insulating partition can be positioned differently, enabling flexible adaptation to various operational requirements without permanently increasing component count.
3Power
If the voltage level is increased to meet power consumption demands, then power capacity is improved, but the cabinet size and weight increase
Solution Approach 1:
The power supply modules are designed with nested structures where the high-voltage cavity and low-voltage cavity are arranged in a compact, space-efficient manner. The insulating partition is integrated within the module structure rather than as a separate external component, reducing overall cabinet volume and weight while maintaining high voltage isolation and power capacity.
