Is the 12V Lead-Acid Battery Dead? - Nov 21
Yes, the 12 V lead-acid car battery is dead. Europe has decreed that no new cars will have lead-acid batteries after 2030, creating a considerable challenge for OEMs to find alternative solutions. While this may seem like a daunting task, it also presents a tremendous opportunity to eliminate the environmentally toxic battery while also reducing weight in a vehicle and improving overall efficiency..

Obtaining Highest Efficiency in DC/DC Converter Applications - Nov 21
While improvements in Silicon power devices have been incremental, the introduction of wide-bandgap devices, such as Silicon Carbide (SiC), allow a jump in performance to be attained. Thanks to reference designs, such as Toshiba’s bidirectional DC/DC power supply, design engineers can significantly speed-up evaluation of suitable design approaches and topologies and get up to speed on the intricacies of using SiC...

Designing Transformer Coupled Gate Drive Circuits and Gate Drive Transformers - Nov 21
Metal oxide semiconductor field effect transistor (MOSFET) and Insulated gate bipolar transistor (IGBT) are amongst the most popular, efficient semiconductor devices for switching power supplies. For medium to high power switching applications, dedicated gate drivers are essential, because it would take too long to charge the gate capacitance for the gate of a power switch to be driven by the output of a logic IC...
