The Importance Of Power Conversion Technologies In The Production Of Green Hydrogen


Global demand for green hydrogen is high and rising fast. Some studies predict that the electrical power demand to produce green hydrogen will be 4500 GW by 2050, compared to today’s (2023) electrical power demand of around 25 GW. This exponential growth will be fueled by green hydrogen which will reduce the carbon footprint of existing industries that use hydrogen as a feedstock, and by the ... » read more

A Revolution For Power Conversion Systems — CoolSiC MOSFET


Silicon carbide (SiC) transistors are increasingly used in power converters, placing high demands on the size, weight and/or efficiency. The outstanding material properties of SiC enable the design of fastswitching unipolar devices as opposed to bipolar IGBT devices. Thus, solutions which have been up to now possible in the low-voltage world only (< 600 V) are now possible at higher voltages... » read more

Power/Performance Bits: May 18


Efficient high-voltage power conversion Researchers from École Polytechnique Fédérale de Lausanne (EPFL) and Enkris Semiconductor are working to design new power transistors with the aim of improving power converter efficiency. "We see examples of electric power losses every day, such as when the charger of your laptop heats up," said Elison Matioli, head of EPFL's POWERlab, noting that ... » read more

Don’t Underestimate The Multiphase Buck Voltage Regulator


Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the output during the entire cycle. The higher delivery of current to the output, per cycle, makes the buck converter the most efficient architecture. As one of many examples, modern microprocessors, from ... » read more
