BAP-1318 Driver Board

High Voltage Isolated IGBT Driver Board

The AP-1318 provides a complete, tested, fast time-to-market solution for companies that need to control and interface to High Voltage IGBT modules.

A transformer coupled DC-DC converter provides 5000V isolation while developing only 10pf leakage capacitance between primary and secondary.

Standard Hewlett-Packard fiber-optic couplers provide an intrinsically safe interface and virtually infinite dv/dt between the module and the customers’ control electronics. Euro-style terminal blocks provide a universal connection arrangement to any IGBT.

Short circuit protection is provided by a built-in desaturation detector. A fault signal output is provided if the short circuit protection is activated.
