Power Electronics Inverter Proportional Resonant Control with RCD Load

The application of MATLAB in power electronics has significantly advanced power system design and analysis. A key implementation involves developing and controlling inverters, which are critical components that convert DC power to AC power in modern power systems. The proportional resonant control (PRC) method, also referred to as proportional resonant current control (PRCC), serves as an effective technique for precise inverter output voltage regulation. This control strategy can be implemented in MATLAB using transfer function modeling with resonant compensators tuned to specific harmonic frequencies, typically implemented through algorithms that calculate appropriate proportional and resonant gains for zero steady-state error at target frequencies. Additionally, RCD (resistive-capacitive-diode) loads represent essential testing components in power electronics, designed to evaluate inverter performance under sudden load variations. MATLAB simulations of RCD loads incorporate diode switching models and RC network equations to replicate real-world transient response scenarios, enabling developers to validate control algorithms through scripts that model load step changes and analyze harmonic distortion using FFT analysis functions.
