The demand having a snubber circuit in the power supply topology leads to specific verification methods during the design to obtain a proper and reliable design. Learn how in this AppNote.
A known problem for electronic developers: No matter what they develop, nothing works without current and voltage. Learn how to create a customized and reliable power supply in just 5 steps and what tools are available.
The reverse recovery of SiC MOSFET body diodes differs du to its unique characteristics from that of Si pn-diodes. The output capacitance and the commutation stray inductance play a significant role in fast switching circuits.
The research deals with power cycling reliability of power electronic devices under application close conditions. An advanced testing approach is presented. The results are underlined by 3D-simulations, which allow a proper physical understanding.
Highly reliable interconnect technologies are increasingly used to achieve much higher reliability or enable the device to operate at elevated temperature. These benefits, however, evolve new challenges for the qualification process.
This paper presents a novel current source gate driver for SiC MOSFETs with adaptive functionalities that aims to improve controllability of turn-on/off delays, di/dt and dv/dt compared to conventional totem-pole voltage source gate drivers.
In the solid state transformers with medium voltage SiC-Devices, it is possible to achieve very high efficiency, although designing a sufficiently high switching frequency in order reduce filter elements, volume and mass of the transformer.
Learn why the control loops of most PFC converters are overlooked and how a small amount of time spent early in design and testing the control loop can save plenty of headaches and get the first stage of your power supply working optimally.
Find out how to meet demanding safety, power efficiency and high reliability requirements in today’s advanced power, EMC and signal line applications in a helpful new eBook.
There is no universal charger for all kinds of batteries, since distinct industries focus on different technical and commercial requirements. This article summarizes the needs of industrial and automotive chargers as well as topologies to meet them.
To reduce our carbon footprint by electrifying society, massive deployment of renewable energy sources has become mandatory. This requires grid-tied energy storage system to balance energy production and consumption demands, to help grid stability.
Nowadays the use of lithium-ion batteries is growing very quickly in numerous fields of application, including high performance electric vehicles as well as grid-tied power converters for the integration of renewable energy.
Wide band-gap power semiconductor devices such as SiC and GaN devices break thermal operating limits and switching speed limits of the Si semiconductors.
Many publications have already dealt with the unwanted parasitic turn-on (PTO) of semiconductor devices and how to get rid of it. But in the same-titled paper, it was shown that high power applications may even benefit from a small PTO.
Without semiconductors, the world would be a very different place; we would have no electronic hand calculators, microwave ovens, digital alarm clocks, cellphones, personal computers, electronically controlled transmissions, or washing machines.
