PCB balances supercapacitors

Advanced Linear Devices is aiming at series-connected supercapacitors with precision dual-channel automatic voltage balancers and over-voltage protectors. Called the SABMBOVP2xx family of products, they are small PCBs based around the firm’s ALD9100xx ICs, with added current-boosting output fets. ALD9100xx ICs (circuit below) include two voltage-dependant current sinks that conduct heavily above a certain voltage – acting ...

Researchers seek dc power grid circuit breakers

Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient than AC (see below), but high-power dc is far harder to interrupt than ac – there is no current zero crossing in ...

Imec develops thin-film monolithic NIR and SWIR image sensor

Imec has developed a thin-film monolithic image sensor that captures light in the near-infrared (NIR) and short-wavelength infrared (SWIR). Based on a monolithic approach, the process promises an order of magnitude gain in fabrication throughh  put and cost compared to processing today’s conventional IR imagers, while at the same time enabling multi-megapixel resolution. To date, infrared ...
