When it comes to alternative energy, I have been a big fan of storage. Alternative energy will not be viable for large-scale power delivery to the grid without storage. My friend Clyde knows of my obsession with storage. He suggested I look into GE's new wind turbines that come with storage attached.
NuWaves Engineering announces the release of the NuPower Xtender Linear Bidirectional S-Band Power Amplifier (PA) module, model number NW-LBSSPA-10W-2.2-2.5, designed for use with half-duplex RF transceivers operating amplitude-modulated waveforms (e.g. OFDM, QAM).
Nearly all of the research on multitasking to date has studied its effects on individuals. Researchers have not yet paid much attention to the effects of multitasking on organizations, but there are good reasons to believe that multitasking has similar effects at an organizational level. After all, people do not typically work independently in organizations
TDK Corporation announces two new series of EPCOS aluminum electrolytic capacitors in extremely compact snap-in designs. The dimensions of the new B43640* and B43644* series are 22 x 25 mm to 25 x 55 mm (diameter x height), making both series significantly more compact than previous series for identically rated voltage and capacitance values.
Are batteries replaced too soon or too late? The answer lays in reliability concerns, service strategies and economics. While most batteries are replaced too late, Dr. Imre Gyuk, manager of the Energy Storage Research Program at DOE, says that every year roughly one million usable lithium-ion batteries are sent in for recycling with most having a capacity of up to 80%.
PowerGate LLC announces the release of the Cosel TUNS50 and TUNS100 AC/DC switching power supplies in miniature footprints using the industry standard ¼ Brick and ½ Brick packages for PCB Mount applications. They offer the leading power densities available for PCB mount, AC/DC products....
Power Integrations introduced CHY100, the first AC-DC wall-charger interface IC that enables designers of mobile devices to implement the Quick Charge 2.0 protocol from Qualcomm. Launched earlier this year, Quick Charge 2.0 enables users to charge mobile devices up to 75% faster than when using conventional technology.
To help designers meet this challenge, Fairchild Semiconductor developed the next-generation TinyBuck regulator family, consisting of integrated POL regulators that incorporate a constant on-time PWM controller and driver with high-side and low-side MOSFETs.
Pulse Electronics Corporation launches a series of low-loss, flat-coil surface mount planar transformers to deliver high efficiency power to applications with tight height constraints. This technology uses a copper fill factor that is twice that of a PCB so the direct current resistance (DCR) of the primary winding is reduced by 50%....
