過去十年來，電動車控制器經歷了材料與技術的升級。隨著電動車越來越追求「輕薄短小」與「高效率」，控制器的設計也必須跟著進化。為了讓電動車跑得更好、零件更不佔空間，工研院把控制器裡笨重的「薄膜電容」做了甚麼改變呢？
📘 在本期「智慧綠能車輛技術專輯」，特別邀請工研院機械所李承和副組長與Uma Sankar Rout工程師，為您解析如何成功為下一代更輕、更強的電動車心臟（100 kW/L）鋪好路！
Design Evolution of an 800 V SiC Traction Inverter Toward 100 kW/L Power Density
As electric vehicles continue to evolve toward slimmer, lighter, and higher-efficiency designs, traction inverter technology must advance accordingly. One of the key challenges is reducing the size of bulky DC-link film capacitors while maintaining high performance and reliability.
In this article, ITRI introduces a new approach: replacing conventional film-capacitor technology with a compact ceramic-based PLZT capacitor bank. This design reduces volume, improves power density, and supports the development of next-generation 800 V SiC traction inverters.
In this issue of "Smart Green Vehicle Technology Special Issue", we invited Howard Li, Deputy Director of ITRI’s MMSL, and Engineer Uma Sankar Rout to share the technical details behind this development and explain how it contributes to lighter, more compact, and more powerful EV controllers approaching 100 kW/L.
