NewTrend · silicon-carbide advanced static var generator
Product overview
NewTrend Y-ASVG-SiC uses silicon-carbide power devices for combined reactive-power, 2nd–50th harmonic-current and three-phase unbalance compensation. Rated reactive capacity is 37 or 50kvar at AC220V, or75 or100kvar at AC380V. Wall-mounted and rack-mounted configurations support 3P3W/3P4W. The catalogue specifies30kHz switching, overall efficiency at least98% and peak efficiency at least98.5%.

Operation
- The ASVG connects in parallel with the load and injects controlled compensation current for reactive power, current harmonics and three-phase unbalance.
- Select individual or combined compensation functions. Individual harmonic compensation covers the 2nd through 50th orders.
- Neutral-line zero-sequence filtering capacity is stated as three times the phase filtering capacity for neutral-connected installations. Confirm combined-duty and harmonic-current requirements for the chosen reactive rating.
Typical applications
- Industrial and commercial distribution with reactive and nonlinear loads
- Data centres, UPS feeders and variable-speed-drive installations
- Three-phase installations requiring reactive, harmonic and load-unbalance compensation

The photographs show exact SiC wall-mounted and rack-mounted enclosures from the original catalogue, retaining safety labels and source image detail. The catalogue maximum of800kvar refers to an eight-module cabinet system, not a single-module rating. Dimensions retain the printed W×D×H sequence. Installation and wiring must be performed by qualified electricians.
