The grid current feedback signal is obtained using a Hall effect sensor while the grid voltage sensing is performed using a voltage transformer. The two signals are then reported to the 0/3.3V voltage range required by the A-D converters of the STM32F103xx microcontrollers, by means of standard circuitry based on operational amplifiers.
The startup voltage of the auxiliary power supply is 18 V while the maximum voltage is 55 V. The STM32F103xx supply voltage is scaled down from the +5 V bus using a low drop linear regulator. Five feedback signals are used by the microcontroller in order to fully control the system.

Common high-frequency inverter circuit configurations include: Key design factors for high-frequency inverters: Switching frequency – Higher frequency allows smaller filter components but increases losses. Optimize based on tradeoffs. Filter components – Smaller inductors and capacitors possible at high frequencies. Balance size versus performance.
The inverter bridge contains power switches like IGBTs or MOSFETs. The switches turn on and off at high speed to generate high-frequency pulses. An LC filter smoothens the pulses into sinewave AC output. The output frequency depends on how fast the switches cycle on and off. Common high-frequency inverter circuit configurations include:
The inverter circuitry can also provide features such as power control and overload protection. The high frequency inverter-based welding machines are typically more efficient and provide better control of variable functional parameters than non-inverter welding machines.
