The behavior is analyzed in regime through RMS value and voltage harmonic distortion, and transient according to IEC62040-3. Both cases for loads of different nature and power equal to the nominal UPS. For development of the prototype was used the IGBTs SKM75GB128D triggered by driver SKHI23-12R and the control has be implemented in a fixed-point DSP TMS320F2812.314-321porClassic controlDC-AC power convertersuninterruptible power systems (UPSs)ResenhaWOS:000429106500002Acesso abertoWOS000429106500002.pdf48317899018238490000-0002-9984-9949
