Technical FAQs 4

What is frequency inverter?

Frequency inverter, also named as VFD, is a kind of power control equipment adopting frequency conversion technology and microelectronics technology to control AC motor by changing the motor power frequency.

What is the difference between low frequency and high frequency inverters?

In fact, low frequency inverters can operate at the peak power level which is up to 200% of their nominal power level for several seconds, while high-frequency inverters can operate at 150% power level for a small fraction of a second.

What is the difference between power inverter and frequency inverters?

The power inverter is a device that can convert DC into AC and the frequency inverter is a component used to change the AC frequency. The power inverter can convert DC power (battery, accumulator jar) into AC power (sinusoidal wave of 220V and 50 Hz), and the frequency can also be adjusted.

What is the efficiency of an inverter?

Efficiency of Inverters The efficiency of an inverter indicates how much DC power is converted to AC power. Some of the power can be lost as heat, and also some stand-by power is consumed for keeping the inverter in powered mode. The general efficiency formula is: where P AC is AC power output in watts and P DC is DC power input in watts.
