73V three-phase inverter

How many kW can a 3 phase string inverter run?

Therefore, higher switching operation is desirable to reduce the size and cost of the system. Building a single inverter of 6 kW up to 350 kW and connecting them in parallel to reach power levels up to 20 MW is common. Infineon offers a wide range of solutions for 3-phase string inverters. Usually, these inverters are rated from 6 kW up to 350 kW.

What is a three phase bridge inverter?

This article outlines the definition and working principle of three phase bridge inverter. 180 degree conduction mode of operation, formula for phase & line voltages of three phase inverter is also explained in this article. A three phase bridge inverter is a device which converts DC power input into three phase AC output.

How many thyristors are in a 3 phase inverter?

A basic three phase inverter is a six step bridge inverter. It uses a minimum of 6 thyristors. In inverter terminology, a step is defined as a change in the firing from one thyristor to the next thyristor in a proper sequence. For getting one cycle of 360°, each step is of 60° interval.

What is a three-phase inverter module?

This module has a three-phase diode based rectifier input stage, a three-phase IGBT based inverter output stage, an IGBT based brake chopper and an NTC thermistor integrated inside the module. In this design the rectifier stage is unused and provision is given to power the three-phase inverter stage directly with a DC power supply.

What is the conduction mode of 3 phase inverter?

180° Conduction Mode of Three Phase Inverter: In 180° conduction mode of three phase inverter, each thyristor conducts for 180°. Thyristor pair in each arm i.e. (T1, T4), (T3, T6) and (T5, T2) are turned on with a time interval of 180°. It means that T1 remains on for 180° and T4 conducts for the next 180° of a cycle.

What type of inverter does Infineon offer?

Infineon offers a wide range of solutions for 3-phase string inverters. Usually, these inverters are rated from 6 kW up to 350 kW. For power up to 20 kW, Infineon’s discrete IGBTs, CoolSiC™ MOSFETs, and CoolSiC TM Schottky diodes are the preferred choice to achieve the best price-to-performance ratio.
