A test circuit for producing a fail signal if a clock path driver circuit develops an AC or DC defect. In the simplest embodiment, this test circuit comprises a time delay block for providing a delayed clock signal and its complement and with a delay that exceeds the signal propagation time...
Chapter 15 AC and DC Equivalent Circuit Modeling of the Discontinuous Conduction Mode 这一章我们关注discontinuous conduction mode (DCM)的小信号模型. 在DCM, Switch的平均电压和电流成正比, 满足欧姆定律, 因此可以用一个lossless resistor, Re(d)代替. Diode的平均电压和电流表现为功率源, 其功率=Re上的功...
Simple AC to DC Circuit - Capacitor? I have recently put together a makeshift pool filter for my wife's wading pool. I used a 5 gal bucket with upholstery fill fabric for the filter, PVC piping to transfer the water out of the pool, through the filter and back into the pool and my...
An AC-DC Converter circuit is a device that converts alternating current (AC) to direct current (DC). This type of circuit is commonly used in electronic devices to provide power for their internal components. In this article, we will discuss the design and implementation of an AC-DC ...
A more stable and double mode will be achieved in the proposed circuit. Key words : flyback;zeros crossing point detect;short;open 对负载的保护以及因负载失效(短路或断路)而对电源的保护是设计中需要考虑的很重要的方面[1-2]。在反激式变换器中,当负载变化超出一定范围,副边二极管续流Is时间过长,且...
DC/DC railway converters are often referred to as bricks, half-bricks, and quarter-bricks. A full-brick measures 4.6 x 2.4 x 0.5 inches, a half-brick measures 2.3 x 2.4 x 0.35 inches, and a quarter brick measures 2.3 x 1.45 x 0.35 inches. But there are also DIP24, 1’’x1’’ ...
The relationship between voltage, current, and resistance in a circuit. Voltage can be either AC or DC, depending on the current that is carrying it. In DC systems, the current never changes direction. It is unidirectional, i.e., it does not change polarity.But in AC systems, the current...
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...
