Most laptops need between 30 and 70 watts to charge. That means they need a lot more power than cellphones. Thankfully the ...

The X-type five-level current source inverter (CSI) features inherent current balancing without using any balancing control schemes. However, it suffers from large dc inductance at high modulation ...

A high efficiency single-stage isolated ac-dc converter topology is proposed in this paper. The proposed converter provides soft-switching, power factor correction (PFC), and output voltage regulation ...
