Description

Technical Field

[0001] The utility model relates to the technical field of all-solid-state induction heating power supplies, in particular to a control system of an all-solid-state induction heating power supply. Background Art

[0002] Induction heating power supply has the highest heating efficiency and speed for metal materials, and it is low-consumption and environmentally friendly. It has been widely used in various industries for hot processing, heat treatment, hot assembly, welding, smelting and other processes of metal materials. The induction heating power supply consists of two parts. One part is the AC power supply that provides energy, also known as the variable frequency power supply. When hot processing the wafer, it is necessary to use the all-solid-state digital induction heating power supply. The series inverter always works in an inductive state, that is, the operating frequency is always slightly higher than the resonant frequency of the load. Due to the change of operating temperature, the electrical parameters of the load coil will change over time, which will cause the inverter to deviate from the optimal operating point, thereby not only increasing the turn-off current value of the MOS tube on the inverter bridge, causing the turn-off loss to increase, but also the power capacity of the inverter cannot be fully utilized. Therefore, it is necessary to set a phase-locked control circuit to realize automatic frequency tracking. There is a voltage fed back by the inverter output. According to the phase relationship between voltage and current, the current signal passes through the phase detection circuit, corresponding to the high and low level signals with a certain duty cycle of the output, and the DC level is obtained after filtering to reflect the fundamental phase shift of the output voltage and current. According to the set phase angle lock value, the regulator outputs the control level and adjusts the output frequency of the voltage-controlled oscillator to achieve automatic frequency tracking. The main functions of the inverter control are to achieve automatic load frequency tracking, inverter starting, provide reliable drive pulses for the inverter power devices, and cooperate with the rectifier side control to ensure the safety of the equipment by controlling the rectifier output voltage when abnormalities occur inside and outside the equipment. The frequency signal taken from the load is passed through the zero comparison circuit to obtain the self-excited square wave signal (frequency automatic tracking timing principle). Before the inverter works, since the voltage and current on the load are both zero, the self-excited signal required for starting cannot be obtained. This equipment adopts externally excited starting. After the inverter is started, when the power supply output voltage reaches a certain value (threshold), the level detection circuit output flips, and the externally excited signal is converted into a self-excited signal, thereby completing the inverter starting process.
