Power Conversion Systems Enabled by SiC BiDFET Device

March 15, 2023 by Subhashish Bhattacharya

The BiDirectional Field-Effect Transistor (BiDFET) can enable circuit topologies requiring four-quadrant switches, that were earlier designed using discrete combinations of MOSFETs, IGBTs, GaN HEMTs, and PiN diodes. The monolithic nature of the BiDFET allows lower device count, smaller switch volume, lower inductance, and simpler packaging, and hence more reliable and … [Read more...] about Power Conversion Systems Enabled by SiC BiDFET Device

A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs

January 23, 2023 by Igor Spinella

The ac–dc power supply units providing isolated, regulated outputs operating above 100 W typically require some form of input active power factor correction (PFC) [1] . To achieve this, a popular solution is to combine a boost PFC input stage with an “LLC” converter which isolates and controls the dc output voltage. However, a new, innovative single-stage technique for … [Read more...] about A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs

Practical Realization of GaN’s Capability

June 20, 2022 by John Stevens; Tom Ribarich; Stephen Oliver

The system-level value of wide bandgap power semiconductors of higher efficiency, smaller size and weight, and more sustainable energy usage in our power supplies and motor drives is being demonstrated now. Gallium nitride (GaN) power FETs are replacing silicon (Si) power MOSFETs in applications from 48 V to 800 V. Silicon carbide (SiC) is replacing legacy IGBTs in applications … [Read more...] about Practical Realization of GaN’s Capability

Driven by Density, Efficiency at Low Cost, Power Integration Reaches New Heights

March 1, 2022 by Ashok Bindra

For decades, miniaturization has been the trend in the power supply world. Consumers have been demanding more functions from smaller systems with better performance and reliability at lower cost. Such advances are evident in today’s laptops, tablets, smartphones, industrial drives and a host of other consumer and industrial applications. To meet these demands, the power supply … [Read more...] about Driven by Density, Efficiency at Low Cost, Power Integration Reaches New Heights

Power Electronics Hardware Design for Manufacturability

December 1, 2021 by Grant Pitel and Adam Pitel

Image of a blue chip.

With a small, diverse team of engineers, Magna-Power Electronics can offer over 160,000 different configurations of programmable power supplies and electronic loads, spanning current levels up to 10,000 Adc, voltage levels up to 10,000 Vdc, and power levels up to 3,000 kW. This feat is made possible through tightly integrated engineering and manufacturing teams, minimizing … [Read more...] about Power Electronics Hardware Design for Manufacturability
