Intermediate frequency heating power supply chassis

The invention relates to an intermediate frequency heating power supply chassis. The intermediate frequency heating power supply chassis comprises a trapezoidal housing case, and a cavity inside the housing case is divided into three layers by a transverse metal partition. An upper layer cavity is a control area provided with a control device, a middle layer cavity and a lower layer cavity are divided into three areas by a vertical metal partition. Left and right areas of the middle layer cavity are a trigger area provided with an insulated gate bipolar translator (IGBT) trigger plate; left and right areas of the lower layer cavity are a major loop area provided with a rectification filter circuit, A middle area of the middle layer cavity and the lower layer cavity is a contravariant output area provided with a contravariant circuit. The intermediate frequency heating power supply chassis has the advantages that the intermediate frequency heating power supply chassis effectively reduces an electromagnetic int
