What is the working principle of the power inverter part of the series resonance one-to-two intermediate frequency furnace?

Have you seen the series resonance one-to-two intermediate frequency furnace? How much do you know about it? Then what is the working principle of the power inverter part of the series resonance one-to-two intermediate frequency furnace? Let's take a look at the details of Guangzhou Youzao Introduce it! 1. Series resonance one-to-two intermediate frequency furnace power supply Series resonance one-to-two intermediate frequency furnace power supply adjusts the output power by controlling the frequency of the inverter, the frequency point is increased, the operating point is close to the resonance point, and the power increases. Therefore, the very small adjustment of the frequency will drive the great change of the power. The load voltage of the series inverter is a rectangular wave, and the current waveform is a sine wave; it can work in the self-excited state or in the other-excited state. It adopts the most advanced self-excited series resonance mode, which can start 100% successfully under any working conditions. Series resonance one-to-two intermediate frequency furnace two, series resonance one-to-two intermediate frequency furnace power supply resonance capacitor The resonant capacitor mainly plays the role of providing reactive power, improving the loop voltage, and increasing or reducing the frequency level in the series inverter circuit. The capacitor is made of water. Cooling, cooling the capacitor through external circulating water, is an important part of the LC series resonant circuit. Series resonance one-to-two intermediate frequency furnace 3. The working principle of the inverter part of the power supply of the series resonance one-to-two intermediate frequency furnace The inverter trigger part of this circuit adopts a special sweep frequency zero-voltage soft start, and only needs to take one channel of the intermediate frequency current feedback signal, It is essentially equivalent to its self-excited circuit, which belongs to the average feedback circuit. Since there is no need to add any starting circuit on the main circuit, and the starting process of pre-magnetization or pre-charging is not required, the main circuit is simplified and the debugging process is simple. The starting process is roughly like this. Before the inverter circuit starts, an excitation signal higher than the tank circuit resonant frequency is used to trigger the inverter thyristor. When the given potentiometer is adjusted from low to high, the regulator works to control The frequency of the excitation signal scans from high to low. When the frequency of the excitation signal drops to close to the tank circuit resonant frequency, the intermediate frequency voltage is established, and the detection circuit catches the inverter current signal and feeds it back to the automatic frequency modulation circuit. When the frequency modulation circuit is put into operation, it immediately stops the action of sweeping the frequency of the excitation signal to a low level, and turns to the automatic frequency modulation circuit to control the inverting lead angle, so that the equipment enters a steady state operation.
