New low-profile gate drive transformers suit industrial, medical and solar energy applications

The new MID-GDT transformer series is now available from Wurth Electronics. These low profile gate drive transformers are surface mount with a maximum height of 5.38mm, and operate with a voltage-time product of at least 70 Vµs on secondary windings. These pick-and-placeable transformers feature 1500V isolation, and have an operating temperature of -40C to 125C. “These transformers are designed in such a way that the two critical parasitics for gate drive - leakage inductance and interwinding capacitance - are extremely low which improves the overall performance of the gate drive circuit,” says Suravi Karmacharya, product applications engineer at Wurth Electronics Midcom. These transformers, 750316093 and 750316094, are best suited for industrial power supplies, smart grid power supplies, medical devices, telecom base station power supplies, motor drive control, and solar energy harvesting applications.
