Technical FAQs 4

How to control the output voltage of inverters?

The most efficient method for controlling the output voltage of inverters is to introduce pulse width modulation (PWM). This method doesn't require any extra peripheral components and is an efficient and economical way compared to other methods.

How to choose an inverter voltmeter and current meter?

Since the waveform’s frequency varies on the secondary side of the inverter, it’s necessary to take the fundamental wave’s frequency range into account when choosing a voltmeter and current meter. Inverters can be used to control motor speed in a fine-grained manner by converting DC to AC.

Do you need a volt meter for an inverter?

Consequently, it's necessary to use a true RMS voltmeter (digital multimeter) and current meter (clamp meter). On the secondary side of an inverter, the voltage and current’s fundamental wave includes harmonic components.

What is the difference between a converter and an inverter?

Since different machines have different frequency and voltage requirements, a circuit known as a converter is used to convert AC current from the power grid to a DC current, and then an inverter is used to convert the DC current to an AC current with the frequency and voltage required by the machinery being driven.
