Drives have major function to control motor rotation speed to achieve power modification and efficiency improvement. However, due to nature and principle of drives, there must be many kinds of fast switching semiconductor devices in the system, such as IGBT and MOSET, they can generate high level of HF EM noises when working, such noises not only will affect power supply network, but also will threaten life time and reliability of motors. JONES developed complete product solutions for power supply and controlling part of drive applications, covering from harmonics to conductive emission.
