1. Electrolytic bus capacitors should be mounted as close to the module bus terminals as possible to reduce ringing and

EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins will further improve perfor-

mance.

2. In order to provide good decoupling between VCC-Gnd and VB-VSS terminals, the capacitors shown connected be-

tween these terminals should be located very close to the module pins. Additional high frequency capacitors, typically

0.1µF, are strongly recommended.

3. Value of the boot-strap capacitors depends upon the switching frequency. Their selection should be made based on

IR design tip DN 98-2a, application note AN-1044 or Figure 9.

4. Low inductance shunt resistors shuld be used for phase leg current sensing. Similarly, the length of the traces be-

tween pins 12, 13 and 14 to the corrisponding shunt resistors should be kept as small as possible.

5. Over-current sense signal can be obtained from external hardware detecting excessive instantaneous current in in-

verter.
