Three-phase inverter reference design for 200-480VAC drives (Rev. A) This reference design realizes a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used has a 6-pin wide body package with optical. . However, most 3-phase loads are connected in wye or delta, placing constraints on the instantaneous voltages that can be applied to each branch of the load. The module also introduces a configurable dead time to avoid dead short circuits. A delay time can be introduced to synchronize multiple three-phase PWM block. . Abstract: This paper presents the three phase DC-AC inverter mainly used in high power application such as induction motor, air-conditioner and ventilation fans, in industries in solar power plants. The parameters of the circuit are the following: a switching frequency between 1.
