2.3 DC/DC Power Supply Design
Figure 8: Schematic of the DC/DC Power Supply
M57140-07F is an isolated DC-to-DC converter with an input of DC 20V.It supplies four 21.5V outputs. Isolation is provided
from primary to secondary (V
ISO
2.5 kV
RMS
/min) and also between the secondary (V
ISO
1.5 kV
RMS
/min). The 21.5V outputs
are split into +15V and –6V supplies by 15V diodes D801 to D804. The +15V/–6V supplies are connected to the seven
ACPL-336J to provide bipolar gate drive voltages.
IC9 is a TA7805F voltage regulator to regulate the 20V input to 5V supply for the primary side of the ACPL-336J.
