一种具有单输入双极性对称输出的软开关无变压器DC-DC变换器

In this letter, a soft-switching transformerless dc-dc converter with single-input bipolar symmetric outputs (SIBSO) is proposed, which has positive and negative outputs with equal voltage amplitude and can be used in audio amplifier, bipolar symmetric auxiliary power supply application, etc. Based on the proposed bipolar symmetric outputs cells, the SIBSO dc-dc converter only requires two switche...
