600V connectors suit compact power applications
PROVERTHA has announced that its 600V D-Sub connectors series, especially developed for compact power applications requiring easy and fast cable assembly, has received UL approval. The 600V D-Sub connectors, available in male and female versions, are suitable for use in applications such as drives, painting systems and robots.
Smart USB charger features 10 output ports
A smart ten output, 120W USB charger designed specifically for any electronic device that can be charged from a standard USB output has been introduced by Powersolve. Suitable applications include tablets, smart phones, cameras, MP3 players and power banks.
96–135W AC/DC power supplies meet efficiency Level VI
Providing 96–135W of continuous output power, the PUP121 and PUP136 series of AC/DC switching power supplies have been introduced by Power Sources Unlimited. Enclosed in a 1″ case with an IEC320/C14 or EC320/C6 inlet for world-wide use, the devices meet efficiency Level VI as well as Energy Star EPS2.0 / ErP Lot7.
MMIC power amp eliminates need for RF switches
Analog Devices has introduced the HMC1127 and HMC1126 MMIC distributed power amplifiers. Covering the frequency range of 2-50GHz, these power amplifier die simplify system design and improve performance by eliminating the need for RF switches between frequency bands. Each amplifier incorporates I/Os that are internally matched to 50Ω, facilitating easy integration into multi-chip modules.
MOSFETs save space in DC end applications
Infineon has launched a family of StrongIRFET MOSFETs for DC powered circuits including battery powered circuits, brushed and BDLC motor drives. The MOSFETs offer efficiency for end applications such as power and gardening tools, light EVs, UAVs and e-bikes that demand a high level of energy efficiency but are restricted in available space. This is made possible by the compact Medium Can DirectFET housing featuring a...
The effect of internal phase shift on power measurement
The measurement of electrical power depends on voltage, current and time. All three contribute to the total uncertainty of the measurement. Ben Kemink, Yokogawa, shows how effects can be minimised by careful power-meter design.
Designing the next smart and lower-power applications
Dung Dang, Texas Instruments explains why Texas Instruments introduced the MSP432 MCU to address the power-saving issues while raising the bar for high performance on ultra-low-power MCUs.
Using SiC devices in a three-phase motor drive application
SiC (Silicon Carbide) MOSFET modules with blocking voltages of 1,200V and RDSON values as low as 20mΩ, offer a real alternative to 1,200V Si IGBTs in motor drives. John Mookken and Julius Rice, Cree, explore the economics of using the more expensive SiC module with the performance gains and added complexities at the system level.
GaN - promise to reality
The next generation of power electronics is taking shape, argues Markus Behet, EpiGaN. The wide-bandgap compound semiconductor material is suited for switching devices that operate at high frequencies without suffering major losses.
Broadband power demands energy efficiency
Billions of people worldwide access television, phone and the Internet via a broadband-enabled system, which uses electricity to send and receive transmissions. As the demand for communication access and the sophistication of the networks grows, so does the demand for power, writes Than Le, Alpha Technologies.
