As depicted in the block diagram, IGBTs, MOSFETs or GaNs are mainly employed as a “Switching Component” and considered a basic building block of the inverter. A PWM or SPWM based input signal is generated using a Microcontroller which controls ON/OFF state of IGBTs/MOSFETs/GaNs.
For example, have a look at the graph below. IGBTs provide highest peak power but on the other hand the designer is restricted to lower maximum switching frequency as compared to MOSFETs and GaN. Figure 1: Power and Frequency Overview Taken from ElectronicDesign.Com
When the optimal PV system capacity ratio and power limit value are taken, the annual damage of the IGBT in the photovoltaic inverter is 0.847% and the net increase of power generation is 8.31%, realizing the increase of photovoltaic power generation while the annual damage of IGBT and power generation loss due to power limit is relatively low.
FOM = On Resistance (RdsOn) x Gate Charge (Qg) In the same Voltage range, GaN and MOSFETs provide better FOM as compared to IGBTs. There are various technical features that add to the BOM cost of the application. Due to high Internal (On) Resistance, heating can be a major issue in Inverters which contributes to thermal instability.
