This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.

The widespread usage of powerful energy accumulators (batteries and supercapacitors) is leading to improvements in current management. A bidirectional DC/DC converter can prolong the battery’s life ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

Power electronics converters require negative feedback to provide a suitable output voltage or current for the load. Obtaining a stable output voltage or current in presence of disturbances like input ...

Cheap DC-DC converters have been a boon on the hobbyist bench for a while now, but they can wreak havoc with sensitive circuits if you’re not careful. The problem: noise generated by the switch-mode ...
