BP7B-LS IPM interface circuit reference design 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. The standard interface circuit consists of opto couplers to transfer control signals and isolated power supplies to power the IPM’s internal circuits. For use with L series IPMs in package A and B. BP7A board uses three VLA106-24151 DC to DC converters to provide high side control power for L series IPMs. The low side control power can be supplied by VLA106-24151.
