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
