Abstract A new generation of 4-switch buck-boost controllers enables power system design with very high efficiency and high power density by using inductor DC resistance (DCR) current-sensing techniques. This article explains the benefits of ...

Knowing the mains frequency is important in many industries; the speeds of AC motors, for example, are dependent on it. The motor speed is where F is the mains frequency and P is the number of poles. Since P is a fixed number for any motor, speed ...
