| Abstract |
This paper describes a design example for a switched mode power supply (SMPS) of high power density made in a half bridge push-pull topology. The size of the transformer and output filter is substantially reduced at improved efficiency by operating the converter at high frequency with low losses. This requires careful design and use of special components. The transformer is optimized for low losses and low leakage inductance. The output filter uses ceramic capacitors and single turn chokes with extremely low parasites resulting in low EMI. The realized converter shows an efficiency of 85% for a 250 kHz primary frequency. |
