Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

What is a feedback loop? A feedback loop is the part of a system in which some portion (or all) of the system's output is used as input for future operations. Each feedback loop has a minimum of four ...

The word servo has become synonymous with the words servomotor, servomechanism, and servosystem to indicate a closed-loop controlled system. A servo is most simply defined as any driven mechanism ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...

Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

Good building mechanical design requires a firm grasp of the mechanical engineering fundamentals (thermodynamics, psychrometrics, the fan laws, etc.). The same can be said about the BAS design needed ...
