Abstract :
This article presents the study of an alternating voltage indirect conditioner, showing the main aspects of its digital and analog control. The generation of the sinusoidal reference for the output voltage control loop is discussed, both in analog and digital control, and for that purpose, a digital PLL based on the three-phase instantaneous power theory is proposed. On the analog controlled converter, an output voltage instantaneous control circuit is used. On the digital control proposed in this work, two circuits are used, one for input voltage feedforward, and one for controlling the effective output voltage. Experimental results obtained with a 10 kVA conditioner are presented
