Working Principle

Three-phase 400 VAC mains supply is rectified via internal diode bridge to generate fixed DC bus voltage stored in electrolytic filter capacitors. Microprocessor control circuit generates pulse width modulated gate drive signals to IGBT power modules, converting DC bus voltage back to variable frequency variable voltage three-phase AC output to drive connected induction motor. Sensorless vector control algorithm calculates rotor flux and torque values from measured motor phase current signals to deliver high low-speed starting torque. Internal temperature sensors monitor IGBT and heat sink temperature; hardware overcurrent circuits instantaneously shut down power module operation upon short-circuit detection. Digital input terminals receive external machine run/stop and speed reference signals, while relay output contacts signal fault and operational status to external control systems.
