Power Phase Converters
220V AC to 380V AC voltage converter
Bangzhao Electric’s BZT series power phase converters use an AC-DC-AC circuit structure to convert AC single-phase voltage into industrial three-phase voltage. In industrial and commercial power applications, the demand for converting 220V single-phase electricity to 380V three-phase power continues to grow. These converters utilize power electronics technology and intelligent control algorithms to achieve precise matching of voltage and frequency, establishing themselves as core equipment for resolving power supply bottlenecks in three-phase equipment.
AC input: 220V single phase
AC output: 380V three phase
Reduce Initial Investment and Operating Costs
Replacing traditional dedicated transformer solutions saves over 60% in initial investment. For example, a 5kW converter driving a three-phase motor significantly lowers costs compared to applying for dedicated power lines. During long-term operation, stable voltage reduces equipment failure rates, extends the lifespan of critical components like motors and controllers, and lowers maintenance and replacement costs.
Cross-Border Equipment Adaptation and Market Expansion
Resolves compatibility issues for 60Hz equipment (e.g., imported machine tools from Thailand or Japan) operating on 50Hz grids. A case study of a multinational corporation’s imported equipment adaptation demonstrates that the converter enabled seamless operation without frequency-related failures, supporting the company’s international market expansion.
