Renewable energy generation and its efficient implementation Infineon offers power semiconductors for the whole electrical energy chain. From Solar and Wind to Energy Storage Systems.
A three-phase inverter requires six IGBT gate drivers. You can use individual gate drivers for each IGBT, but a dual-channel gate driver helps with design flexibility and reduces BOM cost.
To understand the inverter and the role of IGBT, MOSFET and GaN, let''s dive in to the basic design of a H-Bridge based single-phase inverter. 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.
Energy storage system cost is mainly composed of battery and energy storage inverter, which together constitute 80% of the cost of electrochemical energy storage system, among which energy storage inverter accounts for 20%.

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.
Most three-phase inverters use insulated gate bipolar transistors (IGBTs) in applications like variable-frequency drives, uninterruptible power supplies, solar inverters and other similar inverter applications.
The new voltage class 2000 V rated IGBT module can meet the requirements based on recent converter designs for renewable energy applications. An increase in the operating Vcc and even system voltages from 690 to 900 V are feasible.
The current rating of the tested IGBT module was 400 A. Figure 2 shows the reverse-bias safety operating area (RBSOA) test waveforms. The IGBT turned off safely at the outermost boundary of the RBSOA (square area within the twice-rated current and rated blocking voltage of 2000 V) under the condition of
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
The Better the FOM, better would be the efficiency. 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.
