最近在设计实例专栏中，人们对一系列以脉冲宽度调制(PWM)控制通用型稳压器(包括线性稳压器和开关稳压器)的简易接口电路产生了浓厚兴趣。这类电路的共通点，是利用稳压器内部的电压参考源，并在稳压器的设定电压分压电阻串联一个分立的FET。VCAednc PWM通过 ...

Abstract: Pulse-width modulation (PWM) of a motor drive at a fixed switching frequency leads to harmonic currents in narrow bands around integral multiples of the switching frequency resulting in ...

Abstract: The dual-active-bridge (DAB) topology is ideally suited for high-power dc–dc conversion, especially when bidirectional power transfer is required. However, it has the drawback of high ...

从这些案例中我们可以看到，前沿技术的发展呈现出两种截然不同的轨迹：一类是量子存储器、类脑计算、固态电池这样在性能参数和应用场景上不断取得突破，并逐步接近产业化的方向；另一类则是脑机接口等技术，尽管科研成果频出，但受制于伦理、监管和商业模式的不确定性， ...

When driving around in video games, whether racing games like Mario Kart or open-world games like GTA, the game often displays a mini map in the corner of the screen that shows where the vehicle is in ...

“你背的不是望远镜，是火箭发射筒。”——几乎每个把8英寸牛反扛上山的天文爱好者，都听过这句调侃。80斤金属筒、1.2米镜筒、易碎的抛物面主镜，让“追星星”变成“撸铁现场”。现在，一盆PLA塑料粒子+一台千元级桌面打印机，就能把同规格仪器压到12斤，成 ...
