摘要

设计并制作了一种小型铁构件感应加热装置。工作线圈的形状与马蹄形加热相匹配。该装置所需的简单性和坚固性排除了主要用于感应加热应用的水冷工作线圈(由铜管制成)的使用。在我们的解决方案中，工作线圈的结构中使用了高频利兹线。输入整流器的一个非传统的概念与低直流链路容量被使用。这种方式可以实现足够高的功率因数，而无需任何额外的PFC电路。采用MOS-FET半桥双作用逆变器对串联谐振槽进行激励。对所设计的感应加热器进行了系统描述，包括一些重要的细节。

Apparatus for induction heating 2.5 kW using a series resonant circuit

A device for induction heating of smaller iron components was designed and constructed. The shape of the work coil was matched to horseshoe heating. Required simplicity and robustness of the device excludes the use of water cooled work coil (made of copper tube) which is mainly used in the applications of induction heating. A HF Litz-wire was used in the construction of the work coil in our solution. A non-tradition conception of the input rectifier with a low DC-link capacity is used. This way a sufficiently high power factor can be achieved without any additional PFC circuit. A double acting inverter using a MOS-FET half-bridge is used for exciting the series resonant tank. The system description of the designed induction heater is presented including some important details.
