Silicon carbide active power filter development

Improve product competitiveness by integrating advanced technologies belonging to two companies, including silicon carbide power device applications.

The proliferation of non-linear type power electronics based loads in a wide range of applications from adjustable speed drives to hospital diagnostic systems has had a significant impact on the quality of electric power systems. Problems include variety of electrical disturbances, which may originate in harmonic distortion and have different effects on sensitive loads. As a result more industrial and commercial facilities try to protect themselves by investing more in power quality improvement equipment. Energy users try to improve productivity through the reduction of power quality problems resulting in production interruptions and at the same time to maximize profits. The severity of power quality problems in power networks has made necessary the increased use of harmonic filters, which not only reduce the current and voltage harmonics, but also can regulate voltage and improve balance between phases in three phase systems. Many power quality solutions are available on the market today, so the obvious question for a consumer facing a particular power quality problem is which equipment provides a better solution. Active Power Filters (APF) have proved to be an important alternative to compensate for voltage and current disturbances in the power distribution systems. Currently they are based on Pulse Width Modulation technology converters and connect to low and medium voltage distribution systems in shunt configuration. Shunt Active Power Filters operate as a controlled current source and can perform one or more of the functions required to compensate for power disturbances and to improve power quality. Their performance depends on the power rating, the disturbance measurement accuracy and the speed of response. Increasing use of harmonic generating adjustable speed drives and a rising demand for power quality is driving the market growth for harmonic filters. The global harmonic filter market was worth USD 608.2 million in 2013 and is expected to grow at a rate of 7.7% CAGR from 2014 to 2020, reaching USD 1,015 million by 2020 [1]. Passive harmonic filters have dominated the market to date with Mirus’ offering being among the most effective with a growing market share. Properly designed passive filters will remain a popular solution for harmonics due to their lower cost and simplicity but there are many applications where a good shunt Active Power Filter is a better alternative. The market for both solutions will continue to grow. With strong product offerings in both passive and active power filters, Mirus and Medcom would build on their reputation as global experts in harmonic mitigation and power electronic converters. With a new active power filter offering, Mirus and Medcom could leverage their power system expertise to quickly grow market share.
