When compared to conventional AC or CD technologies, the High Frequency Inverter Spot Welder offers greater weld uniformity. It is a high speed digital adaptive feedback that regulates weld current, voltage, or power.
It can be utilised as a single operator benchtop device with one of the numerous weld heads and is also ideally suited for integration into partially or entirely automated resistance welding systems.
The Global High Frequency Inverter Spot Welding Machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A 20kHz switching frequency high-power inverter spot welding power supply is developed; secondary rectification makes use of a full wave rectifying circuit of single-coil and double inductors, double tubes, and can significantly increase the switching frequency with the present device.
The integrated high frequency transformer is built with the ability to efficiently reduce a number of parameters that affect output power while simultaneously increasing output current.
A spot welding power supply with an inverter has power levels close to 90kVA. The power of today’s inverters is evolving in the direction of high frequency, low voltage, and enormous current.
In literature, the inverter frequency is even brought up to 10 kHz for the current inverter resistance welding power supply. The volume of the transformer will significantly decrease as inverter frequency advances, and an integrated transformer will be created.
This will enable the integration of a soldering turret and a transformer and increase benefits such as control precision and other benefits, which can further emphasise benefits such as energy efficiency, small volume, lightweight, and quick response.
It is challenging to convert alternating current to direct current and rectify, particularly in the case of high frequency, high power, due to the spot welding machine’s high output power (dozens to hundreds of thousands of volt ampere), large current (thousands of ampere), and low voltage (only a few volts).
