    1. Medium Voltage Variable Frequency Drives

      The medium voltage variable frequency drive, or simply called as VFD or AC drive, is the backbone in the field of energy conservation and emission reduction. This adjustable speed drive is widely used for normal motors of fans, pumps, compressors, etc. Adopting a new type of IGBT with advanced microcomputer control,

    1. Medium Voltage Soft Starter

      Our medium voltage soft starter is a kind of electrical device applicable to the startup of various heavy-duty motors ranging from 3 kV to 11 kV. It is able to restrict the starting current of the large motors to 1.5 ~ 4 times their rated current.

    1. Static Synchronous Compensator / STATCOM

      Our static synchronous compensator, or simply STATCOM, is especially designed to meet the market demands for high power impact loads like rolling mill, ladle furnace, heavy-duty hoist, electric arc furnace, etc. It adopts cascaded multilevel inverter circuit.

    1. Static VAR Compensator / SVC

      Reactive power, measured in var, compensation or control is an important part in a power system to maximize power transmission capability, to minimize power transmission loss, to stabilize the power system, and to maintain the supply voltage.

    1. Thyristor Switched Capacitor BanksOur thyristor switched capacitor banks (TSC/TSF) with high-speed switching capability are designed to support the supply voltage of distribution systems, and eliminate the harmonic current produced by the connected loads, on the basis of DSP control technology and instantaneous power control theory.
    1. Active Power FilterNon-linear loads have been widely used in recent years. Yet, the quality of power supply is seriously affected due to their non-linear, impactive and unbalanced characteristics. Before the application of power electronic components ...
