Questions & Answers

Q: What are the different types of inverters based on the nature of the source?

There are voltage source inverters (VSI) and current source inverters (CSI). VSI uses a ripple-free DC voltage source, while CSI converts voltage into current and applies it as a current source.

Q: How can inverters be classified based on their configuration?

Inverters can be series, parallel, or bridge inverters. Series inverters connect thyristors in series, parallel inverters have a push-pull configuration, and bridge inverters connect thyristors in an anti-parallel arrangement.

Q: What are the different types of output waveforms in inverters?

Inverters can have square wave output, which can be converted to sine wave or other forms. Other types include cosine square wave and pulse width modulated (PWM) output waveforms.

Q: What power semiconductor devices can be used in inverters?

Inverters can utilize SCR, transistor, power BJT, MOSFET, or IGBT. The choice depends on factors like frequency requirement, power application, and switching speed.

Summary & Key Takeaways

• Inverters can be classified based on the nature of the source, such as voltage source inverters (VSI) or current source inverters (CSI).

• Classification can also be based on the configuration of the inverter, including series, parallel, or bridge inverters.

• Inverters can vary in terms of the nature of the output waveform, ranging from square wave inverters to sine wave inverters.

• The power semiconductor devices used in the inverter, such as SCR, transistor, power BJT, MOSFET, or IGBT, can determine its performance.

• Lastly, the commutation circuit used to switch the thyristors in the inverter can be categorized as either series or parallel.
