Static Digital Converter from single to 3 phase

‌Product Overview‌

This industrial-grade power converter utilizes a digital control algorithm to precisely convert single-phase to three-phase power, achieving an output voltage fluctuation of <1%. It is particularly suitable for applications with stringent power quality requirements, such as precision machining equipment and test platforms. Key advantages include: 1) Utilizing IGBT modules and a DSP digital signal processor for coordinated control, it ensures conversion efficiency ≥95% across the entire power range (3-200kW); 2) A built-in real-time harmonic compensation system achieves THD ≤3%, exceeding the IEEE 519 standard; and 3) a protection system that includes graded fuse overload protection, IGBT shoot-through protection, and dynamic voltage regulation (OVP/UVP range ±15%). UL/cTUVus certified, IP20 rated, and operating temperature range of -10°C to +50°C, it can be seamlessly integrated into automated production line upgrades or laboratory power system renovations.

Product Advantage

High-Efficiency IPM Technology: Utilizing the sixth-generation efficient IPM intelligent module from Mitsubishi, Japan, this converter ensures high efficiency and stable performance. Its robust protection mechanisms against short circuits, overload, and overheating guarantee safe and reliable operation, with a service life extending up to 15 years or more.

Flexible Start Modes: Offering two start modes—Reduction Voltage Start and Variable Frequency Start—users can customize the start mode based on their load requirements. This flexibility not only enhances user convenience but also reduces the need for additional frequency converters, thereby lowering equipment investment costs and simplifying wiring and control procedures.

Pure Sine Wave Output: The converter delivers a pure sine wave output with excellent transient response (less than 50ms) and minimal waveform distortion. This results in higher conversion efficiency and stable output voltage, ensuring optimal performance for connected devices.

Electrical Isolation with Low-Frequency Transformer: By employing a low-frequency transformer, the converter achieves complete electrical isolation between the input and output voltages, effectively preventing interference and ensuring a clean power supply.

SVPWM Space Vector Algorithm: Leveraging the SVPWM space vector algorithm, the converter achieves high conversion efficiency, high instantaneous power, and low no-load losses (exceeding 94% efficiency with minimal no-load loss). This enhances overall system performance and reduces energy waste.
