Radiated EMI specifications for power supplies

Radiated emissions affect a power converter’s EMI signature at high frequencies. The upper test frequency for radiated tests extends to 1GHz or higher depending on the specification, and much above that for conducted emissions. Performing radiated EMI measurements, while not as straightforward as conducted emissions tests, is necessary for compliance testing and can easily become a bottleneck in a product’s development cycle.

Advantages of load switches over discrete MOSFETs

In this video, Alek Kaknevicius, Applications Engineer at Texas Instruments, discusses TI’s integrated load switches and what advantages they bring over a discrete MOSFET solution. In general, load switches are put in between a power supply and a load. When the load needs to be on, the load switch is closed. And when the load can be turned off, the load switch is opened.

Taking charge of electric vehicles

A charging station is part of the grid infrastructure installed along a street, parking lot or in a home garage; its primary purpose is to supply the power to the PHEV for charging the battery. An onboard charger is responsible for the final stage of charging the battery pack. It takes the AC power source from the EVSE and transforms the power into the required battery-charging profile.
