反激变压器 变压器设计 效率和EMI
Flyback transformer design considerations for efficiency and EMI • Flyback transformer basics • Review of Flyback transformer losses: o Core loss – dependence on DC bias, duty cycle, wave-shape o Causes of AC copper loss o Proximity effects explained o Leakage inductance & how to estimate it o Effect of snubber clamp voltage on leakage losses o Design optimisation example Choice of wire size, strands, layer stack-up to reduce leakage inductance and proximity effects • EMI o CM cancellation & balancing techniques o Design example
