DYNAMIC COMPENSATION HARMONIC
Sinexcel Active Harmonic Filter can realize 2nd to 50th harmonic compensation, compensation ratio can be set selectively by the customers, output compensation current follows the system harmonic variation, devoted to green power quality.
Different loads generate variety harmonic content which changes dynamically during different working conditions.
Harmonic current decomposition
AHF outputs compensation current
1. AHF synchronously allocates the compensation capacity in real time
AHF self-learns the system impedance characteristics, identify feature of individual harmonic order.
SINEXCEL PIONEER
MODULAR DESIGN
Ultra-compact design, wall and rack-mounted structure and fine capacity distribution can fully meet customers' needs, suitable for space limit application, retrofit projects.
Convenient for transportation and replacement, easy to be integrated into panel.
Flexible engineering cabinet design, plug cabinet, IP54 cabinet, top and bottom cable entrance design to comply with different customers’ needs.
SINEXCEL EARLIEST ADOPTER
3-LEVEL TOPOLOGY
· One more output level, less ripple current content
· Output PWM waveform is more similar to sinusoidal wave, better harmonic compensation effect
· The volume of LCL filter is reduced, beneficial for AHF module design
· Less inductance loss, improving the system efficiency
· IGBT withstand voltage stress cut into half, effectively reduce the switching loss
· Less switching loss of IGBTs, more thermal margin, higher switching frequency
TEN YEARS ITERATION
INDEPENDENT AIR DUCT DESIGN
Upper and lower layer design, IGBT heatsink and inductor, which account for most heat of AHF, are concentrated in the lower layer, forcing air cooling, fast heat dissipation, and do not affect the upper PCBA
Upper PCBA auxiliary air duct design, expansion of heat dissipation channel, wide angle heat dissipation
PLUG SUITE
Assist customers to build their own plug cabinet Sinexcel can offer AHF unit with plug suite, monitoring system, alarming indications lights, then the customer can build their own plug cabinet on site. Plug cabinet, no wiring, easy for integration and unit replacement, a more convenient and cost-effective solution for our customers
