Enhanced current and voltage regulators for stand-alone applications

State feedback decoupling permits to achieve a better dynamic response for Voltage Source in stand-alone applications. The design of current and voltage regulators is performed in the discrete-time domain since it provides better accuracy and allows direct pole placement. As the attainable bandwidth of the current loop is mainly limited by computational and PWM delays, a lead compensator structure is proposed to overcome this limitation. The design of the voltage regulator is based on the Nyquist criterion, verifying to guarantee a high sensitivity peak. Discrete-time domain implementation issues of an anti-wind up scheme are discussed as well. Laboratory tests in compliance with the standard for UPS systems (IEC 62040-3) are performed to validate the theoretical analysis.
