Technical FAQs 4

How to control AC voltage in an inverter?

The most efficient method of doing this is by Pulse Width Modulation (PWM) control used within the inverter. In this scheme the inverter is fed by a fixed input voltage and a controlled ac voltage is obtained by adjusting the on and the off periods of the inverter components.

What are the parameters of an inverter circuit?

The parameters of the circuit are the following: a switching frequency between 1.95 kHz. The task of an inverter is to convert a DC input voltage into an AC output voltage whose amplitude and frequency can be adjustable.

What is inverter modulation?

Modulation involves adjusting the on and off duration of inverter switches under constant input DC voltage to achieve controlled inverter output voltage. The most popular modulation technique used in inverters is pulse width modulation (PWM). Space vector modulation is often used in inverters due to its ease of implementation.

What are voltage source inverters (VSIs)?

Since the invention of the MOSFET, Voltage Source Inverters (VSIs) have been far more widely used in various applications compared to Current Source Inverters (CSIs). As a result, advancements in modulation and control techniques in power electronics have primarily focused on VSIs.
