It’s all about materials

Ally Winning, European Editor, PSD

Welcome to the May edition of PSD. This year seems to be constantly busy and the time is flying in. Maybe it is because the industry is on the crest of a wave at the moment, or it may be that the number of important events is increasing and we are constantly in the lead up to another one. This month, we start

Advanced Cooling and Efficient Semiconductor Technology is a Winning Combination

Figure 1: 3D model depicting Dual Cool technology

Power engineers often face seemingly conflicting and almost impossible challenges. As system designers add more features and functionality to newer product generations, so the system requires more power, but has less space available to generate it. While there are many techniques available to manage heat, forced
