Description

Transformer device for reducing magnetic field interference

本發明係有關於一種變壓器裝置，特別是一種降低磁場干擾之變壓器裝置。The present invention relates to a transformer device, in particular to a transformer device for reducing magnetic field interference.

變壓器非常常見，是應用法拉第電磁感應定律而能夠升高電壓或降低電壓的電子電路；變壓器通常包含兩組或兩組以上的線圈，主要用途是升降交流電的電壓、改變阻抗及作為分隔電路，因此變壓器非常的重要。Transformers are very common. They are electronic circuits that can increase or decrease voltage by applying Faraday's law of electromagnetic induction. Transformers usually contain two or more sets of coils. The main purpose is to increase the voltage of alternating current, change the impedance and act as a separate circuit. Therefore, Transformers are very important.

有些電子產品的變壓器的初級側和次級側之間規定要有比較高的隔離，例如使用在某些醫療器材的變壓器，此時變壓器的線圈的線材長度往往需要拉長延伸才能達成上述變壓器的初級側和次級側之間的被規定要有的比較高的隔離。The primary side and the secondary side of the transformer of some electronic products are required to have a relatively high isolation, such as the transformer used in some medical equipment. A relatively high isolation is specified between the primary side and the secondary side.

然而，上述初級側和次級側之間規定要有比較高的隔離的變壓器的缺點是變壓器的電流所產生的磁場干擾大，因此造成了紋波雜訊較多、電磁干擾較大等等問題。However, the disadvantage of the above-mentioned transformer with relatively high isolation between the primary side and the secondary side is that the magnetic field interference generated by the current of the transformer is large, thus causing problems such as more ripple noise and greater electromagnetic interference. .
