In order to obtain different output powers to control the temperature of the heating load, the controlled parameter is actually the rms value of the intermediate frequency voltage across the load. The rms value of this voltage is similar to the DC voltage U output by the chopper. Therefore, by controlling the voltage value of the chopper, the output power of the inverter can be controlled, that is, the temperature of the heated load can be controlled.

IGBT module is a modular semiconductor product that is packaged by IGBT (insulated gate bipolar transistor chip) and FWD (freewheeling diode chip) through a specific circuit bridge. The packaged IGBT modules are directly used in inverters, UPS uninterruptible power supplies and other equipment, and have the characteristics of energy saving, convenient installation and maintenance, and stable heat dissipation. Currently, most of these modular products are sold on the market. With the advancement of the concept, such products will become more and more common in the market. IGBT is the core device for energy conversion and transmission, commonly known as the "CPU" of power electronic devices. As a national strategic emerging industry, it is widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment.

Generally, semiconductor devices with rated current exceeding 1 ampere are called power semiconductors. They block voltages ranging from a few volts all the way up to tens of thousands of volts. Among the many power semiconductor devices, the power diode is a relatively simple device, but it is also a common basic device that is most widely used in power circuits. It is not only used in simple rectifier circuits, but also often used as freewheeling diodes (FWD for short). In simple single-phase half-bridge inverter circuits, it is matched with controllable switching devices and used in anti-parallel to continue to maintain inductance. current on the load, preventing voltage spikes due to sudden drops in current. The use of this kind of FWD exists in many applications such as switching power supplies, variable frequency power supplies, uninterruptible power supplies, and variable frequency motor drives.
