High Isolation Gate Drive Transformer, Encaslation Toroid Platform

Pulse is delighted to announce the launch of automotive grade forward gate drive transformer specifically designed for IGBT device switching. The PMG3045NL is a 2W forward transformer which provides a +15V for device switch on as well as a -7.5V for robust switch off.  The encapsulation construction provides 3750KV ac withstand voltage in a compact (15.8×12.5×10.2mm) SMD platform.

This platform satisfies the 10mm min creepage distance and complies with IEC62368-1 for reinforced  insulation. Triple insulated wire is utilized to fulfil the requirements of high reliability in automotive applications.

One typical application is that PMG3045NL could be used in three phases inverter driver system in electric vehicles. The typical input voltage is 15V with 100KHz switching frequency, winding (6-8) provides +15V output with full-bridge rectifier for IGBT switch on, and winding (5-7) provides -7.5V with half-bridge rectifier for switch off. See the application circuit below.
