Chapter 3: System Description
This chapter provides the EB1200-352J specifications and functional description, interfaces, and mechanical details.
3.1 Key Specifications
Table 1 lists the absolute maximum ratings of the EB1200-352J. Note that Table 1 contains only key parameters. Constraints
from ACPL-352J data sheet as well as specifications of other key components must be considered when the EB1200-352J
is used.
3.2 Functional Block Diagram
Figure 2 shows the functional block diagram and Figure 3 shows the disposition of the functional blocks of the EB1200-352J
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
Figure 2 . Low-voltage side connectors aimed for signal interface and power supply of digital
side of ACPL-352J drivers are presented in green.
