FAQ on axial flux motors: Part 3
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. Part 1 of this series examined the axial-flux motor (AFM) in detail and compared it to the very widely used radial-flux motor (RFM). Part 2 of this FAQ continued the exploration of AFMs and RFMs. This final part […]
High-capacity, 100 V automotive MLCCs in miniatures sizes for 48 V architectures
TDK Corporation has expanded its CGA series of multilayer ceramic capacitors (MLCCs) to 2.2μF in 2012 size (2.0 x 1.25 x 1.25mm – L x W x T) and 4.7μF in 3216 size (3.2 x 1.6 x 1.6 mm – L x W x T), with the industry’s highest capacitance*, as 100V products for automotive […]
100 V Trench Schottky diodes boost efficiency in high-frequency power converters
STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including […]
FAQ on axial flux motors: Part 2
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. This part of the FAQ continues the exploration of AFMs and RFMs. The first part examined the axial-flux motor (AFM) in more detail and compared it to the very widely used radial-flux motor (RFM). The final part […]
