Shunt Active Filter with Average dq Frame control algorthim

Simulation circuit of Shunt active filter mitigates harmonics and reactive power

Nonlinear and linear load is connected to the three phase supply.
Supply current is non sinusoidal.
Shunt Active Filter is switched at 0.08sec. Now Supply current is sinusoidal and in phase with the supply voltage.
Power factor is near to unity and THD is reduced to 5%

Load parameter can be varied to study different types of load characteristics
