Voltages source inverter ( VSI)
A voltage source inverter is a constant voltage source which is having negligible impedance. In these inverters the amplitude of output voltage does not depend on the load but the wave form of load current and its magnitude depends upon the nature of load impedance. The output voltage of VSI can be controlled by changing the power factor of the circuit the frequency of the inverter and the pulse width.
Suppose we have a coil wound onto a ring of material with relative permeability µ r . Provided that the relative permeability µ r >> 1, then the magnetic flux lines will s
