Description

The STIL02 is connected in parallel with the bridge diode and the inrush power resistor Ri (fig. A2). During start up, the two unidirectional ASD™ power switches of the STIL02 are opened. The inrush current flows through the diodes of the bridge and the external inrush power resistor Ri. Since the main converter turns ON, the auxiliary power supply coupled with the main transformer, supplies the energy required to close the two power switches of the STIL02. At the normal state, the two bottom diodes of the bridge rectifier and the two unidirectional switches of the STIL02 rectify the AC line current.

When the STIL02 is used with a PFC boost converter, the inrush current circuit remains active after a short AC line dropout (see fig. A5). In that configuration, since the AC line disappears, the PFC controller and the auxiliary power supply of the STIL turns OFF. The two switches of the STIL are opened. The output bulk capacitor Cb is discharging and it is providing the energy to the main converter. When the AC line recovers, the two switches remain opened and recharging inrush current of the capacitor Cb is deviated and limited through the resistor Ri. When the capacitor is charged, the PFC turns ON again and the two switches of the STIL switch ON. More details on the design and operation of the driver circuit of figure A5 can be found in the application note "AN1600 - STIL: Inrush Current Limitation Device for Off-Line Power Converter".
