Mains-connected boost Power Factor Correction (PFC) circuits are employed in order to meet EMI standards. The EMI filter together with the boost inductor has to attenuate the High Frequency (HF) ...

This application note presents EMI filter modifications when replacing L6562 with CS1501. It presents an introduction of the CS1501, then the filter structure, test results and the changes to the EMI ...

Electric vehicles (EVs) use several kilowatts of energy to drive the ac synchronous propulsion motor from 400-V lithium-ion (Li-ion) batteries. The dc/dc circuits used to charge the batteries generate ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...

Fig 1.The disadvantage of the CCM approach is that since the circuit is switched while forward current is flowing, it exhibits high diode reverse recovery power loss. This requires the use of fast ...
