Three-Mode Variable-Frequency ZVS Modulation for Four-Switch Buck+Boost Converters With Ultra-high Efficiency

This article introduces a three-mode variable-frequency zero-voltage switching (ZVS) modulation method for the four-switch buck+boost converter. This method makes this circuit concept well suited for applications, such as wireless power charging of electric vehicles, where this circuit operates as a power buffer between the resonant converter...

Bio Loop Plug-in: a prototype to close the loop for food waste in a neighborhood scale

One-third of the food produced is wasted while the demand for food is increasing worldwide. The food supply in the consumption phase is not only the last chain but also wastes the most. Yet the majority of residents in the Netherlands have still underestimated this number. Therefore, the design aims at recycling and reusing the food waste on the...
