Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...

The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...

Microprocessor-based devices require a regulated power supply unit that detects the loss of input power and continues to supply power for the length of time it takes to complete a memory backup. One ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
