Description

邊繞式的繞線變壓器Edge wound winding transformer

本創作是有關一種繞線變壓器,特別是一種邊繞式的繞線變壓器的構造。The present invention relates to a winding transformer, and more particularly to a side winding type winding transformer.

對於功率變換器而言(例如:電腦電源供應器或是切換式電源供應器),如何增加功率密度,縮小尺寸以及提高開關頻率(切換頻率),是功率變換器的設計者所關心的問題。提高開關頻率雖然可以減少例如變壓器和濾波器的尺寸,但是開關損耗會對高頻工作造成不利的影響,為了減少開關損耗,遂有諧振切換技術被提出使用。For power converters (eg, computer power supplies or switched power supplies), how to increase power density, reduce size, and increase switching frequency (switching frequency) is a concern for designers of power converters. Increasing the switching frequency can reduce the size of, for example, transformers and filters, but switching losses can adversely affect high frequency operation. In order to reduce switching losses, resonant switching techniques have been proposed.

一般而言,LLC諧振式功率變換器包括:一個具有金屬氧化物半導體場效電晶體(MOSFET)的控製器、一個LLC諧振網絡和一個整流器網絡。控製器透過脈衝頻率調製(PFM)的方式,交替切換兩個MOSFET,並隨負載變化而改變工作頻率,調節輸出電壓Vout。LLC諧振網絡包括:兩個諧振電感(Lr和Lm)和一個諧振電容(Cr)。LLC諧振式功率變換器有著零電壓開關(ZVS)、器件的電壓應力低等特點,非常適合在要求高效率和大功率電源的應用。隨著LLC諧振式功率變換器的廣泛應用,應用於LLC諧振式功率變換器的LLC變壓器的設計也愈來愈受到重視。已知應用於LLC諧振式功率變換器的LLC變壓器,通常會把磁性元件Lr和Lm集成在一個變壓器內, 利用變壓器的漏感(漏磁電感)作為Lr,利用變壓器的磁感(激磁電感)作為Lm,可以減少磁性元件的數目。In general, an LLC resonant power converter includes a controller with a metal oxide semiconductor field effect transistor (MOSFET), an LLC resonant network, and a rectifier network. The controller alternately switches the two MOSFETs by means of pulse frequency modulation (PFM), and changes the operating frequency as the load changes, adjusting the output voltage Vout. The LLC resonant network includes two resonant inductors (Lr and Lm) and one resonant capacitor (Cr). The LLC resonant power converter features zero voltage switching (ZVS) and low voltage stress on the device, making it ideal for applications requiring high efficiency and high power supplies. With the wide application of LLC resonant power converters, the design of LLC transformers for LLC resonant power converters has received increasing attention. Known for LLC transformers used in LLC resonant power converters, the magnetic components Lr and Lm are usually integrated into one transformer. By using the leakage inductance (leakage inductance) of the transformer as Lr and the magnetic inductance (magnetizing inductance) of the transformer as Lm, the number of magnetic elements can be reduced.

傳統的繞組變壓器都具有一固定的鐵芯,其上繞有初級(又稱一次)與次級(又稱二次)的線圈,線圈的繞線方式通常是將初級線圈和次級線圈以同軸的關係繞在同一個鐵芯,其中一者位於內圈另一者位於外圈,初級與次級的線圈在電力方面互相分離且互相絕緣,以這種方式繞線的繞組變壓器,初級線圈和次級線圈初之間具有較佳的耦合密度,因此具有較小的漏感。一般而言LLC的磁感量(激磁電感量)是漏感量(漏磁電感量)的3到7倍,通常要求漏感值較大,換言之,應用於LLC諧振式功率變換器的LLC變壓器應減少變壓器初級側和次級側的耦合密度,才能獲得較大的漏感。Conventional winding transformers have a fixed iron core with a primary (also called once) and secondary (also called secondary) coil wound. The winding of the coil is usually coaxial with the primary and secondary coils. The relationship is wound around the same core, one of which is located on the inner ring and the other is located on the outer ring. The primary and secondary coils are electrically separated from each other and insulated from each other. In this way, the winding transformer, the primary winding and The secondary coils have a better coupling density at the beginning and therefore have a smaller leakage inductance. In general, the amount of magnetic inductance (magnetizing inductance) of LLC is 3 to 7 times the amount of leakage inductance (magnetic leakage inductance), and the leakage inductance value is usually required to be large. In other words, the LLC transformer is applied to the LLC resonant power converter. The coupling density between the primary side and the secondary side of the transformer should be reduced to achieve a large leakage inductance.

另一方面,傳統採用內外兩圈繞線方式的繞組變壓器在運作時,位於內圈的線圈也會有散熱不易的問題。因此,設計應用於LLC諧振式功率變換器的LLC變壓器,需著重於設計變壓器的漏感與磁感,以及設計變壓器初級側和次級側的繞線方式。On the other hand, when the winding transformer of the inner and outer windings is used in operation, the coil located in the inner ring also has a problem that heat dissipation is not easy. Therefore, the LLC transformer designed for the LLC resonant power converter needs to focus on designing the leakage inductance and magnetic inductance of the transformer, and designing the winding method of the primary side and the secondary side of the transformer.
