The Effect of Transformer Leakage Inductance on the Steady State Performance of Push-pull based Converter with Continuous Current

摘要: As a result of the advantages such as high efficiency, continuous current and stability margin, push-pull converter with (PPCWCC) is competitive for battery discharge regulator (BDR) which plays an important role in power conditioning unit (PCU).Leakage inductance yields spike low-ripple PPCWCCs. The operating modes are added due to leakage inductance. Therefore steady state performance affected, embodied current. PPCWCCs suitable BDR can be separated into three types by characteristics. Three representative topologies IIs1, IIcb2 Is3 analyzed order investigate factors on magnitude duration spike. Equivalent sampling method (ECSM) eliminates time delay achieves excellent dynamic adopted prevent disturbance sampling. However, ECSM reduces accuracy telemetry neglecting In this paper, used summarized. error quality quantity, provides foundation offsetting enhancing accuracy. Finally, rate compared experiment results, verify theoretical analysis.
