In induction motor drives, the common-mode voltage appears between the start point of the induction motor and the ground. It causes common-mode current to flow through the motor bearings, which is harmful to the machine’s life. Let’s take a look at some of the other effects caused by common-mode mode voltage in inverters in the upcoming section.
Common examples are refrigerators, air-conditioning units, and pumps. AC output voltage This value indicates to which utility voltages the inverter can connect. For inverters designed for residential use, the output voltage is 120 V or 240 V at 60 Hz for North America. It is 230 V at 50 Hz for many other countries.
In different countries, the applicable AC voltage is different, and most countries use 110v, 120v output inverter voltage. You can confirm on the search engine or see how much AC voltage the home appliance label uses. How can the quality of inverter output voltage be measured?
Inverters come in various configurations, each designed for specific power systems. Common rated input voltages include 12V, 24V, and 48V. The choice depends on the application, the size of the power system, and the available power source. A 12V inverter is commonly used for smaller applications, such as in vehicles or small off-grid setups.
