BP7B – L-Series IPM Interface Circuit Reference Design

Description: The BP7B is a complete isolated interface circuit for six and seven pack low and medium power L-

Series IPMs. This circuit features the VLA606-01R opto-interface IC for isolation of control signals and isolated

power supplies for the IPM’s built-in gate drive and protection circuits. The isolated interface helps to simplify

prototype development and minimize design time by allowing direct connection of the IPM to logic level control

circuits.

Features:

brake control and fault feedback

Power Connectors

Ordering Information: BP7B-LS is a kit containing a bare PCB with one VLA606-01R and four VLA106-24151

DC to DC converters

(For use with L-Series IPMs in package A and B)

BP7B-LB is a kit containing a bare PCB with one VLA606-01R opto-interface IC, three

VLA106-24151 DC to DC converters and one VLA106-24154 DC to DC converter

(For use with L-Series IPMs in package C)

BP7B is a bare PCB only.

Note: User must supply Optocouplers and passive components to fully populate the BP7B (See Table 2)

Applications:

BP7B is designed for use with Powerex L-Series six

and seven pack IPMs: 50A-300A 600V and 25A-

150A 1200V.

Use Powerex VLA106-24151 and VLA106-

24154 DC to DC converters for isolated

control power. See Table 1 for

requirements.
