Abstract: This inrush current is generated typically in unloaded power transformers and at times can attain the value of around 10 times the full load value. In this method it is proposed to use a voltage source PWM converter which is to be connected in series to the transformer that will produce a dynamic resistor in series with transformer and reduce inrush current. This method will be validated using MATLAB Simulations. It is expected that the proposed method removes inrush current substantially .It is expected that this strategy will be easier to implement because it has simple control method and requires no information of the transformer parameters, power on angle circuit breaker and measurement of residual flux and so on.
