(2) d1 requires approximately the same voltage of power modules. (3) if reverse recovery time of d1 is long, pin1 is applied high voltage. in that case, counterplan for protection which insert a zener diode between pin 1 and 6 is necessary like above diagram. (4) in case pin 2 is operating, the ctrip is expected to be wired as close as possible from pin 2 and pin 4. (less than 5cm coming and going) operation of protection circuit application circuit example operation flow on detecting shortcircuit input signal is off clear alarm ye s no start detection of short circuit gate shutdown output fault signal (1) in case the gate voltage is ?h? and the collector voltage is high, this hybrid ic will re cognize the circuit as short circuit and immediately reduce the gate voltage. besides, put out an error signal (?l?) which inform that protection circuit is operating at the same time from pin8. (2) when the output rises, the controlled time detect short circuit (typ 2.6us) is set up so that on-time of igbt can be secured properly. it is possible to adjust that time by connecting the capacitor (ctrip) between pin2 and 4. vla531 14 13 1 2 5 4 6 vcc vee rg d1 4.7k vin (5v) ctrip 47uf 47uf dz1 hc04 etc. 30v 8
