Design and Analysis of Control Strategies for a Stand-Alone VSI with LC Output Filter
The primary constraint limiting the possible band-width of current regulators in digital systems is pulse width modulated (PWM) delays. Control system delays, in particular, have a negative impact on converter performance. This paper proposes effective designs of the proportional integral derivative and proportional resonant controllers for the two-level voltage source inverter (2L-VSI) in association with the LC filter. Both strategies include a design process for the voltage and current loops that considers the closed-loop transfer functions. The cross-over criterion is used to develop both control strategies while taking the needs of the application into consideration. The theoretical analysis is verified by simulation tests that are carried out in compliance with UPS standards.
