Abstract EN
It is necessary for three-level explosion-proof inverters to have high thermal stability and good output characteristics avoiding problems caused by power devices, such as IGBT, so it becomes a hot and difficult research point using only one control algorithm to guarantee both output characteristics and high thermal stability.
Firstly, the simplified SVPWM (Space Vector Pulse Width Modulation) algorithm was illustrated based on the NPC (neutral-point-clamped) three-level inverter, and then the quasi-square wave control was brought in and made into a novel holographic equivalent dual-mode modulation algorithm together with the simplified SVPWM.
The holographic equivalent model was established to analyze the relative advantages comparing with the two single algorithms.
Finally, the dynamic output and steady power device losses were analyzed, based on which the power loss calculation and system simulation were conducted as well.
The experiment proved that the high-power three-level explosion-proof inverter has good output characteristics and thermal stability.
