Chapter 3: System Description
This chapter provides the EB600-337J specifications and functional description, interfaces, and mechanical details.
3.1 Key Specifications
Table 1
lists the absolute maximum ratings of the EB600-337J. Note that
from ACPL-337J data sheet as well as specifications of other key components must be considered when the EB600-337J
is used.

3.2 Functional Block Diagram
Figure 2
shows the functional block diagram and
gate evaluation board. In the middle of the system is a power integrated module (yellow), and its DC terminals are connected
to a DC bus capacitor bank (blue). The DC bus can be supplied with an AC power source by using an integrated three-phase
diode rectifier, or externally through the DC bus terminals. If a diode rectifier is used, the negative side of the diode rectifier
(N_REC) and the negative side of the DC bus (–DC_BUS) must be shorted. The DC bus terminals as well as other power
terminals are shown in grey in
side of ACPL-337J drivers are presented in green.
