Functional Description
The STIL04 isconnectedin parallel with the bridge diode and the inrush power resistor Ri (fig. A2). During
start up, the two unidirectional ASD™ power switches of the STIL04 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 theSTIL04. At the normal state,the twobottom diodes of the bridgerectifier and
the two unidirectional switches of the STIL04 rectify the AC line current.
When the STIL04 isused with a PFC boostconverter, the inrush current circuitremains active after a short
ACline dropout(see fig.A5). Inthat configuration, since the AC line disappears,the PFCcontroller andthe
auxiliary power supply of the STIL turns OFF. The two switches of the STIL are opened. The output bulk
capacitorCb isdischarging and itis providingthe energy tothe mainconverter.When theAC line recovers,
the two switches remain opened and recharging inrush current of the capacitor Cb is deviated and limited
throughthe resistorRi. Whenthe capacitor ischarged, thePFC turnsON again and the twoswitches ofthe
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”.

LIGHTNING SURGE IMMUNITY (IEC61000-4-5)
During lightning surge transient voltage across the AC line, over current and over voltage stress are appliedon allthe components of the powersupply. TheSTIL04 can sustain a maximumpeak surgecurrent of
500Aas defined by the combinewaveform generator (8/20µswaveform as shownin fig. A3 and A4).
Special recommendations for the lightning surge immunity:
1 - Check that the maximum peak surge current in the STIL stays below the limit specified above.
2 - Check that no over voltages are applied on the STIL and the bridge diode.
3 - In order to reduce the dynamic current stress (dI
/dt) through the structure of the STIL04, it is recom-
out
mended to connect a differential mode choke coil in front of the STIL and the bridge diode.
More details and design guidelines are provided in the application note “AN1600 - STIL: Inrush Current
Limitation Device for Off-Line Power Converter”.
