For a more safe project, check outHow to Build a DC Fan Circuit. DC is much safer than AC voltage than a wall outlet. And both fans carry out pretty much identical functions. In both, the blades spin alike, just on different types of power. AC runs on AC voltage. DC runs on DC ...

大型转换器通常以超过 90% 的能效等级工作,而使用 1 W 至 2 W 范围的小型 DC/DC 转换器难以实现这种额定能效,因为每个转换器具有固定的静态功耗,而小型转换器的此类功耗比率比大型转换器相对更高。因此根据实际的功率和拓扑,经优化的 DC/DC 转换器能效约为 85% 至 92%。 但在这种情况下,仅关注满负载时的...
Why do we need a 12V AC to DC converter for LED? Fig.1 LED lights are highly popular due to their energy efficiency and long lifespan. However, they require a specific voltage and current to function. AC voltage fluctuates, which can cause damage to LED lights. Therefore, a 12V AC to...

摘要传统双有源桥单级AC-DC变换器的移相调制难以实现全范围软开关,开关管损耗大,效率难以进一步提高。针对此问题,该文提出一种基于临界电流模式(BCM)的调制策略,将移相和调频相结合,实现所有开关管的零电压开通,从而有效地降低了开通损耗。该文分析单级式双向AC-DC变换器的临界电流调制基本原理和软开关实现条件,并...
