300kW SiC half-bridge offers 99% efficiency

Silicon carbide is a route 99% efficiency in induction heating drivers, claimed Cree as it introduced a 300A, 1.2kV half-bridge module. Bolting straight into a industry-standard 62mm footprint, it includes two 5mΩ SiC mosfets and two SiC free-wheeling Schottky diodes, that drop 1.7V at 300A. “The power module is pin-compatible to 62mm half-bridge modules, including IGBT modules rated at 450A

DC-DC converter in a BGA has 2kV isolation

Linear Technology has introduced a 2.5W output DC/DC converter with 2kVAC galvanic isolation in a 9mm x 15mm x 4.92mm ball grid array (BGA) package. The isolated transformer, control circuitry, power switches, and a modest amount of input and output capacitance are encased in the BGA package. A minimum creepage distance of 4.3mm on the package exterior supports operation at

Protect A Power Factor Controller Circuit And Battery Charger From Voltage Surges

In a typical ac-dc power supply, diode bridges do not control inrush current due to the output capacitor sudden charge at line plug-in. A high inrush current can cause several issues for the system like component failure (fuse, bridge diode, etc.), but it also represents an excessive current stress for the power grid. If nothing is implemented to limit the

Taking The Ion Out Of Lithium-ion To Increase Power Storage

Lithium-ion batteries are everywhere because today’s technology allows them to hold the most electricity of any other portable power source. But they could hold more if they ditched the ion in the battery’s anode and used only lithium. But lithium alone makes for an unstable battery – until today. Stanford University researchers say they’ve taken a major step toward developing

Sharp Jumps Into Distributed Storage, Targeting 50MW of Behind-the-Meter Systems

California, already the epicenter of distributed solar PV, is also a growth market for behind-the-meter energy storage. Companies like Stem, Green Charge Networks, Coda and the dynamic duo of SolarCity and Tesla are installing big batteries in buildings, mainly on the business case of reducing demand charges for commercial and industrial customers. In the future, those batteries could also help
