WE-PSPA

PUSH PULL & GATE DRIVE TRANSFORMER

WE-PSPA is a small sized power transformer specially designed for Push-Pull and Gate Drive applications.

Space reduction due to its low profile.
Suitable for a great variety of applications thanks to its different turn ratios.
Perfectly reliable for automotive applications because of its automated manufacturing process.

An important parameter of the Push Pull and Gate Drive Transformer is the product of time and voltage, until the core saturates. The voltage-time product V- t (unit: volt-second) is calculated of the inductance L and the saturation current Isat. When selecting a transformer, you should ensure, that enough volt-seconds are available, depending on the frequency and pulse bandwidth of the application.
