8 Things to Consider Before Designing a Gate Drive Transformer· Transformers designed for low coupling capacitance have high leakage inductance which limits PWM slew rate. A large transformer has high coupling capacitance, which causes high circulating currents from dv/dt across the transformer. The transformer requires special construction to meet safety standards for isolation.
