Power Tips #137: Implementing LLC current-mode control on the secondary side with a digital controller

Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current switching on the secondary side in order ...

Power Tips #136: Design an active clamp circuit for rectifiers at a high switching frequency

In vehicle electrical systems, a high- to low-voltage DC/DC converter is a reversible electronic device that changes the DC from the vehicle’s high-voltage (400 V or 800 V) battery to a lower DC ...

[etc] Apparently, many electric clocks tell time based on the power grid's frequency

Not open for further replies. Apparently it is too much of a hassle to maintain a consistent AC frequency. I am unimpressed, electricity producers. And trying to blame it on renewable energy is just ...
