6.6.5 Dead Time (tdead)

In order to prevent arm shoot

through a dead time between high

and low side input ON signals is

required to be included in the sys-

tem control logic. Two different val-

ues are specified on the datasheet:

A. tdead measured directly on

the IPM input terminals

B. tdead related to optocoupler

input signals using the

recommended application

circuit

The specified type B dead time is

related to standard high speed

optocouplers. (See Section 6.6.2)

By using specially selected

optocouplers with narrow distribu-

tion of switching times

the required type B dead time

could be reduced.

6.6.6 Using the Fault Signal

In order to keep the interface cir-

cuits simple the IPM uses

a single on/off output to alert the

system controller of all fault condi-

tions. The system controller can

easily determine whether the fault

signal was caused by an over tem-

perature or over current/short cir-

cuit by examining its duration.

Short circuit and over current con-

dition fault signals will be tFO

(nominal 1.5ms) in duration. An

over temperature fault signal will be

much longer. The over temperature

fault starts when the base plate

temperature exceeds the OT level

and does not reset until the base

plate cools below the OTr level.

Typically this takes tens of sec-

onds.

Note:

Unused fault outputs must be prop-

erly terminated by connecting them

to the +15V on the local control

power supply. Failure to properly

terminate unused fault outputs may

result in unexpected tripping of the

modules internal protection.
