Abstract
- This work presents a modified version of the current-fed dc–dc push–pull converter associated with an active clamping circuit for mitigating voltage spikes on the primary-side switches. Unlike the traditional push–pull topology, saturation due to asymmetrical gating signals applied to the active switches is not likely to occur in the high-frequency transformer because the converter allows for connecting a blocking capacitor in series with the primary winding. In addition, the leakage inductance will not cause high voltage spikes on the primary-side semiconductors owing to the clamping capacitors. Since all active switches operate under the zero-voltage switching (ZVS) condition, one can obtain a high efficiency over a wide load range when comparing the structure with its hard-switching counterpart. Experimental results obtained from a laboratory prototype rated at 1 kW are presented and discussed to validate the theoretical claims. [ABSTRACT FROM AUTHOR]
