6 FAQs about [Three-phase high frequency inverter]

What is a high frequency inverter?

In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.

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 output stage of a three-phase inverter?

The output stage of the three-phase inverter primarily comprised a dual closed-loop control system utilizing the SVPWM modulation algorithm, an NPC three-level inverter circuit, an LC filter circuit, and a three-phase load module.
