Overview:
in gate drive and protection circuits is that the entire family outlined
in Table 1 requires only two different interface circuit designs. The
standard interface circuit consists of opto-couplers to transfer control
signals and isolated power supplies to power the IPM’s internal
circuits. The two circuits are similar except that large L-Series IPMs
in package D utilize separate control grounds on the low side to
minimize ground bounce induced noise. As a result these devices
require six isolated power supplies. The Powerex BP6A reference
design is an example of this circuit.
packages A, B, and C have a common control ground for all three
low side IGBTs. This permits use of a single low side supply so that
only four isolated supplies are required. Interface circuit details for
these devices are available in the Powerex BP7A reference design
application note.
Isolated DC to DC Converters:
power supplies, Powerex has introduced the VLA106-24151 isolated
DC to DC converter shown in figure 2. The VLA106-24151 operates
from a 24V DC supply and produces an isolated 15V DC output at up to
100mA.
between the primary and secondary side. The BP6A board uses six
VLA106-24151 DC to DC converters to supply control power for the L-
Series IPM.
