The SVG provides 2 functions:

1. Reactive power compensation covering inductive to capacitive mode
2. Load balancing between phases

The SVG is very robust and is immune to network pollution stress. It utilize a step-less compensation output that is able to adapt to changes in the network condition continuously. 

The SVG provide the following benefits compared with traditional Switched Capacitor Bank system:

1. Fast response time of less than 10ms
2. No risk from system resonance 
3. Precise compensation
4. Operate seamlessly between inductive to capacitive compensation
5. Less than half the space requirement vs conventional cap bank of same capacity
6. Less output capacity derate during line voltage drop
7. Rated capacity remains steady over 10 years MTBF

SVG can be applied in networks that require robust and rapid responding compensation. The following are some typical applications:

1. Network with many VFD driven motor loads
2. Welding and Arc Furnace operating network
3. PFC to be mounted right next to motor load in tight space
4. Diesel genset network running in island mode with non-linear loads
