This study exploited the hysteresis current control (HCC) with optimal switching frequency for interleaved boost converter to improve the power factor of wind energy conversion system (WECS) exclusively for DC microgrid applications. By fact that output power from WECS is variable due to unpredictable wind speed, where the HCC suffers with range of switching frequency, high switching loss, large input current ripple and poor power factor. To overcome the aforementioned problem, an automatic tuning procedure has been developed for proportional–integral–derivative (PID) voltage regulator to achieve optimal feedback gain of filter inductor current and thereby optimal switching frequency is maintained with good power factor, low harmonic distortion and improved efficiency. Additionally, the robust PID voltage regulator guarantees the stability and investigated through bode plots. Hardware prototype model is implemented in the laboratory standards with Spartan 3AN field programmable gate array control board. The experimental results obtained are confirming the theoretical background aspects of the operating regimes.
