Prof. Junichi Itoh

The requirement of the high power density for power converters becomes stronger and stronger. Nowadays, the volume of the cooling system is smaller and smaller due to appearing wide band gap, i.e. SiC and GaN power semiconductor devices. In contrast, passive components such as inductors and capacitors dominate the volume of the power converters.

In this presentation, the minimization technologies for passive components are introduced with different kinds of circuit topology and control. The ac-to-ac direct power converters not requiring a smoothing DC capacitor, the active power decoupling circuit reducing the smoothing DC capacitor in the single-phase ac converters, the current discontinuous mode control reducing interconnection inductors and FRT control for minimizing the inductor size will be presented.
