4 FAQs about High-frequency machine front-stage 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.

Which power supply topologies are suitable for a high frequency inverter?

The power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).

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. Based on the SVPWM algorithm, the maximum amplitude of the three-phase voltage output was Udc2 /3 ½.

What are the components of an inverter output stage?

The output stage consisted of DC bus capacitors C2 and C3 and three-phase bridge arms (each phase bridge arm comprising four IGBT power devices and two clamping diodes), with an LC filter installed between the inverter output and the load for filtering.
