I am using a dc supply rectified output from the transformer to make my dc link for inverter circuit.I am using ir2113 and igbts for h bridge switching.
when i powered on my ir2113 supplies,pwm for igbt is zero(no turn on state for igbt ) the dc link capacitor starts charging.i tried 2 pin connection to eliminate possible grounding current.but still didnt succeed...any suggestion or help ?
 

Yes, the DC bus will be charged to about VCC by the Vbs quiescent current. Just normal operation.
