Three-phase PWM inverters have a similar operating principle to single-phase inverters but use six power switches arranged in three legs. The control unit generates three separate PWM signals, one for each phase. These signals are used to control the switching of the IGBTs to produce three-phase AC power.
High Efficiency Conversion: Three-phase inverters utilize advanced PWM technology and efficient power switching devices to achieve high-efficiency conversion from DC to AC. Their conversion efficiency typically exceeds 90%, significantly higher than traditional power conversion equipment.
PWM inverters can be broadly categorized into single-phase and three-phase types, each with distinct structures and applications. Single-phase PWM inverters consist of two main parts, the DC power source and the inverter bridge, typically use a full-bridge configuration consisting of four power switches, usually IGBTs and MOSFETs.
The three-level NPC PWM inverter is a type of multilevel inverter that provides a higher quality of output wave form compared to traditional two-level inverter.
