Conventional converter transformer at high frequencies, which have localized hot spots in central core. Therefore, in order to reduce thermal effects, when the conventional converter transformer operating frequency increases, it is necessary to correspondingly reduce the magnetic flux density, increasing its volume. This makes it impossible to use it to do high power density power. Ideal for low output voltage converters for high-frequency machine, its step-down ratio is high. When conventional converter transformer with high frequency hardening machine, usually a turn output winding Xiamen frequency machine, it takes about 32 turns of the primary winding. Such Shandong frequency machine, you need a multi-layer primary winding arrangement, and thus between the leakage inductance and winding large capacitance, skin and proximity effects and serious adverse factors are present in the converter transformer. High frequency machine described in our continent frequency product called high frequency, as the name suggests is to achieve an ultra-frequency device, usually of international standards in 40.68MHz, 27.12MHZ, 13.56MHz different devices collectively referred to as high-frequency frequency machine. Mainly used in modern industrial welding equipment needed in the market needs we can often see: "Metal frequency machine, plastic high-frequency machine, bentwood high frequency machine", their role is mainly used for different materials not the way to be welded.
