Superior Linear Units (ALD), a California producer of analog expertise, has created a six-channel supercapacitor computerized balancing (SAB) printed circuit board (PCB). ALD says the board, referred to as SABMB6, can stability any measurement supercapacitor with zero added energy dissipation.
Every PCB can stability as much as six supercapacitors stacked in a collection, starting from six to lots of of supercapacitors with capacities from zero.1 to three,000 Farads in 12 volts and better. ALD says the ultra-low energy dissipation allows energy-efficient supercapacitor balancing.
ALD president Robert Chao stated, “Moderately than specializing in the DC voltage balancing, the ALD technique manages leakage present and is impartial of the cell capacitance.”
ALD notes that battery builders are more and more utilizing six 2 V cells for 12 V purposes, which frequently requires builders to stack supercapacitors in collection or in parallel. By permitting as much as six linked cells, ALD says the SABMB6 reduces the danger of a brief circuit and battery failure.
Every six-channel PCB makes use of three SAB MOSFETs that mechanically stability the leakage and voltage of every supercapacitor cell linked in collection. Reverse-biased exterior clamping energy diodes (Schottky rectifiers) will be put in when crucial throughout every SAB MOSFET to clamp surge present transients.
ALD already manufactures two- and four-channel SAB PCBs, and the boards will be cascaded with mix-and-match configurability to stability a number of collection stacks.
