Article 3: Selecting Reliable Thyristor Modules for UPS Systems

1. Introduction: Matching Thyristor Parameters to UPS Needs

In UPS systems, dual thyristor modules are chosen based on their ability to maintain load stability, absorb faults, and offer seamless industrial phase control. They must handle High surge current, deliver low on‑state voltage, and operate in compact, thermally stable packages—especially in sectors like elevator, HVAC, and textile automation.

2. Optimized Structure and Finishing

2.1 Compact Package Design Benefits

Compact package thyristors allow designers to save space without sacrificing current capacity. In tight enclosures, such as those in HVAC or UPS cabinets, the module’s reduced footprint ensures flexibility in design and effective High surge current absorption.

2.2 The Role of Anodizing in System Longevity

Anodizing improves thermal dissipation and corrosion resistance. These surface properties support extended use in environments like power converter systems, where heat and vibration could degrade uncoated modules, thus preserving low on‑state voltage over time.

3. Key UPS-Specific Electrical Parameters

3.1 High Surge Current Tolerance

UPS systems are exposed to load switching and grid reentry, demanding strong High surge current capability. Dual thyristor modules built for these spikes protect sensitive hardware and maintain voltage consistency across load changes.

3.2 Accurate Phase Control

A UPS requires smooth industrial phase control to ensure backup power aligns with active loads. This is particularly vital for systems controlling motors in elevator drives or fans in HVAC systems where precise phase balance prevents mechanical failure.

4. Application Adaptability and Integration

4.1 Battery Charging and Soft-Start Systems

UPS batteries require regulated input. By using thyristor modules with soft-start features, the system can limit inrush current at startup. This protects both the battery charger and connected electronics, especially in precision devices.

4.2 Industrial Use in Radar and Textile Equipment

High-end equipment like radar units or textile looms rely on uninterrupted current. A dual thyristor module in a UPS system with proper packaging and surface treatment ensures long-term reliability in such high-demand operations.
