Control Boards

Control boards are the brain of drive and inverter systems and are responsible for generating precise command signals for the power section, executing control algorithms, monitoring system parameters and communicating with the user interface or industrial network. These boards typically include a microprocessor or DSP, analog circuits (operational amplifiers, filters), ADC/DAC converters, memories and isolation circuits. Specialized diagnostics cover testing of PWM and gate-drive signals, inspection of analog and digital feedback circuits, analysis of software and hardware behavior under fault conditions, and debugging with specialized tools. Professional repairs include replacement of faulty components with exact parameter matching, reconstruction of damaged circuits, reprogramming or updating of firmware, calibration of control loops and complete functional testing under real conditions. These services ensure that the control board provides precise commands, fast response and long-term stability for the power section after repair.
