Power supplies from phone chargers to EVs to industrial machinery rely on semiconductors, either in discrete packages or integrated into power modules, to deliver power. APEC 2024 was full of power sources and components. The roundup below highlights regulators, switches, and power semiconductors. We also highlight wireless power delivery and chargers. Be sure to see […]

Zonal automotive power distribution can dramatically improve efficiency, weight, and cost: part 2
If something can’t go on, it won’t; supplying the automobile’s voracious electrical demands from a 12-V battery is an example of this reality. Topology changes affect the battery source Due to the 12-V issues, many newer ICE vehicles and nearly all EV/HEVs also have a 48-V battery. This battery serves loads more efficiently and is […]
Zonal automotive power distribution can dramatically improve efficiency, weight, and cost: part 1
If something can’t go on, it won’t; supplying the automobile’s voracious electrical demands from a 12-V battery is an example of this reality. Today’s cars — whether based on the traditional internal combustion engine (ICE), some form of hybrid electric vehicle (HEV), or even a pure electric vehicle (EV) — are loaded with electronics, sensors, […]
APEC 2024: Power to the data center
Data centers power the world, or does the world power data centers? According to one report, datacenters currently consume 2% of the world’s electricity and that could increase to 8% by 2030. Much of that electricity arrives at the load as low voltage, high current. For example, a single IC, processor, graphics processor, AI chip, […]
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 […]
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 […]
FAQ on axial flux motors: part 1
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. For many electrical and even mechanical engineers, motor selection is somewhat of a mysterious process. You can understand their basic principles and operation. Still, the real-world design considerations of their flux paths, poles, materials, and tradeoffs seems […]
Danisense to exhibit at APEC 2024
Danisense will be exhibiting at APEC 2024 at Long Beach Convention Center, Long Beach, California, USA, from 25th to 29th Feb 2024 at booth 834 of its US distribution partner GMW Associates. On display will be several highly precise and reliable current sense transducers from Danisense. Featuring a very large aperture of 41.2mm, the DN1000ID […]
Murata launches three power systems
Murata announces a trio of products, including a new charge pump IC and two step-down DC-DC converters designed to solve power challenges for consumer devices and low-output voltage applications Murata, at the 2024 Applied Power Electronics Conference (APEC), announced the launch of three new power product solutions designed to help solve the challenges, constraints, and […]
400 V/600 V ESD withstand-capable rectifiers offering both polarity protection and ESD protection
New TSD Series automotive-qualified 400 V / 600 V rectifiers target a wide range of lighting, industrial, communications, security, and many other applications requiring robust ESD protection. Taiwan Semiconductor announces its new line of automotive-qualified rectifiers featuring ESD withstand capability. The TSD Series rectifiers simultaneously provide repetitive peak reverse voltage (VRRM) of up to 600 […]
