A typical implementation of a solar inverter employs a full-bridge topology using four switches (Fig. 2). Here, Q1 and Q3 are designated as high-side IGBTs while Q2 and Q4 are des-ignated as low-side
To build a 3-level NPC topology, three modules (one half bridge module and two chopper modules) are required as shown in Figure 1. Modules A and C are the chopper modules and the
rter. The three level inverter offers several advantages over the more common two level inverter. As compared to two level inverters, three level inverters have smaller output vo. tage steps that mitigate
The new 7th generation IGBT chips have led to further improvements in power density for 3-level applications. This applies to PCB-based systems in which the new generation 7 950V IGBTs
Fuji Electric has developed a new high-power IGBT (insulated gate bipolar transistor) module having high isolation voltages which could apply to three-level inverter as one of multi-level inverter systems.
