Rectifier Transformer
Product Overview
Core Product Type: Focuses on phase-shifting rectifier transformers—a key device for supplying multi-phase rectified power to medium and high-voltage frequency converters. It is developed to meet the localization demand of phase-shifting rectifier transformers amid the mature development of frequency conversion speed regulation technology.
Technical Principle: Adopts the extended delta phase-shifting principle. Through multiple secondary windings with different phase-shift angles, it can form rectifier transformers with equivalent phase numbers such as 9-phase, 12-phase, 15-phase, 18-phase, 24-phase, and 27-phase. This design effectively optimizes rectification efficiency and suppresses harmonics (consistent with the multi-pulse rectification technology common in the industry).
Derived Capabilities: Developed based on the technology of non-encapsulated dry-type transformers, it can be matched with two-way converter manufacturers to provide two-way converter transformers (extending application scenarios to energy storage and other fields requiring bidirectional energy flow).
Certifications & Compliance: Meets international standards including CE, UL, ISO, IEC, IEEE, and KEMA, ensuring compatibility with global market requirements.
