Abstract

A single-sensor double-frequency output resonant circuit comprises a single sensor and an auxiliary resonant circuit which are connected, wherein the single sensor is formed by connecting a sensor equivalent inductor L and a sensor equivalent resistor R in series; the auxiliary resonant circuit is formed by connecting a resonant inductor L1 and a resonant capacitor C1 in series and then connecting the resonant inductor L1 and the resonant capacitor C1 with a resonant capacitor C2 in parallel. The designing method of parameters of the single-sensor double-frequency output resonant circuit includes the steps that first, the topological structure of the resonant circuit is determined, and then, according to the impedance characteristics of the resonant circuit, a resonance angular frequency equation of the resonant circuit is built, and the resonant circuit parameters are obtained. The single-sensor double-frequency output resonant circuit is simple in structure, all the parameters are designed totally according to deduction of mathematical logical relations without any additionally-added man-made supposed constraint, no computational items are ignored, the parameters are designed strictly, the circuit resonant frequency determined by the parameters is clear and accurate, the energy utilization rate of a double-frequency output induction heating power source is increased, the selectable frequency range of the double-frequency output resonant circuit is also correspondingly widened, and the double-frequency output performance of the resonant circuit is improved.

Description

technical field [0001] The invention belongs to the technical field of induction heating power supply, and specifically relates to a single-inductor dual-frequency output resonant circuit; the invention also relates to a design method of the resonant circuit. Background technique [0002] The induction heating device is a device that uses the principle of electromagnetic induction to convert electrical energy into heat energy. In the application of induction heating, the induction coil is not in direct contact with the workpiece to be heated, and the alternating current in the coil generates an alternating magnetic field of the same frequency. An induced current (eddy current) is generated inside the heated workpiece to heat the workpiece. Existing studies have shown that the frequency of the current in the induction coil is an important factor in determining the heating performance of the workpiece. Since the current frequency is inversely proportional to the heating thick...
