Wolong is a leading manufacturer of high-voltage drives with 25 years of experience and a global installed base for industrial pump, fan, blower, compressor, and conveyor applications. We offer essential VFDs to help reduce energy consumption and ease maintenance costs for the Mining, Oil & Gas, Water & Wastewater, Power Generation, and general processing industries. Best-in-class 18-pulse phase shift transformer as standard starting at 1000 HP. Performs with low distortion which lowers harmonics for the local grid, exceeding IEEE 519 and most utility codes. Cascaded H-Bridge is a proven state-of-the-art topology featuring: An IGBT based multi-level voltage source inverter delivering low distortion output. This design eliminates the need for filters and can control legacy as well as modern motors. It is superior to 2 or 3 level inverters and far superior to current source inverter designs. High system reliability with neutral rebalancing. The drive will continue to run if a power module fails so an operator can plan a controlled shutdown. Maintenance is easy with a modular design, allowing fast swap out of power modules. The design also allows front access to all components. Industry-leading power density for an optimal footprint This high power dense system optimizes floor space, and the modular/drawer structure is easy to maintain.
