stil 2/11 functional description in a pfc boost pre-regulator the stil is connected in parallel with the diode bridge and the inrush power resistor. during start up, the two unidirectional asd power switches of the stil are open (figure 3). the inrush current flows through the diodes of the bridge and external inrush power resistor. when the pfc reaches steady state, the auxiliary power supply coupled with the main transformer, supplies the energy required to feed the driver of the two power switches of the stil (figure 4). in steady state, the two dc ground connected diodes of the bridge rectifier and the two unidirectional switches of the stil connected to dc+ rectify the ac line current. figure 3: function description at turn-on figure 4: function description in steady state powerfail feature when the stil is used with a pfc boost converter, the inrush current circuit is active after an ac line drop- out. in that configuration, since the ac line disappears, the pfc controller and the auxiliary power supply of the stil (figure 8) turns off. the two switches of the stil are open. 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 had finished charging, 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 5 can be found in the application note ?an1600 - stil: inrush current limitation device for off-line power converter? . i + pt1 auxiliary power inrush resistor i i ac in pt2 driver out - + bridge driver i inrush resistor auxiliary power pt2 i out ac in + - + bridge pt1 i obsolete product(s) - obsolete product(s) obsolete product(s) - obsolete product(s)

stil 5/11 power losses calculation when the input current is sinusoidal (case of pfc), the conducted power losses can be calculated by us- ing the following formula: if the output average current is 8amps, v t0 and r d of the electrical characteristics table can be used. for different output current please refer to the application note an1600 that provides guidelines to estimate the correct values of v t0 and r d . lightning surge immunity (iec61000-4-5) during lightning surge transient voltage across the ac line, over current and over voltage stress are ap- plied on all the components of the power supply. the stil can sustain a maximum peak surge current up to i peak (i peak = 500a for stil04/stil06 and i peak = 1000a for stil08) as defined by the combine wave- form generator (8/20s waveform as shown in figures 5, 6 and 7). special recommendations for the lightning surge immunity: 1 - check that the i peak 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 out /dt) through the structure of the stil, it is recom- 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?. figure 5: surge test condition p tot v t 0 i out av () r d i ( out av () ) 2 8 ------------------------------------ - ? + ? = iec61000-4-5 stil pt 1 pt 2 i out v out coupling network + surge generator (l evel 1, 2, 3 or 4) 5vdc 0 + out n driver l figure 6: surge test characterisation for stil04/06 figure 7: surge test characterisation for stil08 1 1 5 s 80a/div i out ipeak=500a 0 amps 8 s 20 s iec61000-4-5 ipeak 1 1 5 s 160a/div i out ipeak=1000a 0 amps iec61000-4-5 ipeak 8 s 20 s obsolete product(s) - obsolete product(s) obsolete product(s) - obsolete product(s)
