From a +/- 1800 volts DC source, a 400-kW, three-phase 3-level inverter delivers variable power to a distribution power system. The inverter output is connected to the 25-kV, 40 MVA, 50-Hz system through a 2200 V / 25 kV transformer. The inverter topology is based on the model described in .
The proposed modelling will be based on online simulation in which the inverter losses are calculated precisely with much less computational efforts. Basically, there are four types of losses in multilevel inverters which are: Conduction loss, Switching loss, OFF-state loss and Gate loss.
The Phase-A leg is implemented using three Half-bridge IGBT with Loss Calculation blocks. Both switching and conduction losses are calculated and injected into a thermal network. The simulation illustrates the achievable output power versus switching frequency for the three-phase, 3-level inverter.
It was found that, at low switching control, the total inverter losses represents about 4% of total power delivered by the inverter. About 62% of total loss occurs while the devices are conducting and only 32% of loss comes from switching. The inverter was controlled by SHE which is a low frequency control.
Abstract—This paper presents an analysis of power semiconductor losses with modulation effects in Three-Level T-type Neutral Point Clamped (3L-TNPC) inverters. In order to avoid errors, a distinction must be made in power loss models between switching devices and specific modulation strategies.
The inverter loss is calculated as follows [42,43]: P tot = P con + P sw = P conIGBT + P swIGBT + P conD + P swD (9) where P con and P sw are conduction losses and switching losses, respectively. The average value of the conduction losses in the insulated-gate bipolar transistor (IGBT) over the switching cycle is calculated as follows [42, 43]: ...
