Getting pure sine waves from electronic inverters
Digital signal processors (DSPs) are being used in switching power supplies able to synthesize pure sine waves for use in high-reliability (hi-rel) military applications. Ruggedized digital inverters were installed in the M1068, a Command Communications variant of the U.S. Army’s M113 family of armored personnel carriers. The original M113 Armored Personnel Carrier was first fielded in Vietnam. To […]

Integrated EMI filter for automotive Ethernet includes 15-kV surge protection
STMicroelectronics’ EMIF02-01OABRY is a highly integrated solution designed to suppress EMI noise in automotive applications employing BroadR-Reach interfaces. This EMI-suppressing low-pass filter includes 15kV ISO 10605 surge protection and is AEC-Q101 qualified. Till now, designers have used discrete components to design EMI filters that are compatible with the BroadR-Reach specification. Because there may be a large dispersion […]
High interest in low-energy communications
Advances in the Internet of Things depend on emerging wireless technologies that use little energy and fit in cramped quarters. It looks as though the success of wearable technology such as smart watches and fitness bands could hinge on low-energy versions of wireless communication technology. The low-energy technology getting the most attention is Bluetooth 4.1 […]
Top power electronics threads on EDAboard.com – November
3V – 5V high current 150A power supply – I have been asked to generate a 100A RMS precise sinusoidal current. It will have negligible burden/load. Luckily I’ve done something very similar in the past where I used a LEM sensor, a dsPIC33, and an inductive load and a current-controlled PWM inverter based on a PI […]
