A detailed technical illustration showing how a Variable Frequency Drive (VFD) converts AC power into DC and then back into controlled AC to run a motor. The diagram displays the full three-stage process: incoming AC waveform on the left, a rectifier block converting AC to DC, a DC bus with capacitor storage smoothing the power, and an inverter module generating variable-frequency AC for the motor on the right. The flow arrows visually connect each stage, clearly demonstrating the power conversion sequence. This educational graphic supports the topic “Does a VFD change AC to DC?” and highlights the advanced motor-control technology used in RAFSUN water pump systems.
