Differences between Low Frequency (LF) Inverters and High Frequency (HF) Inverters

Nov 25, 2020. | By: José González

Inverters can be divided into high frequency inverters and low frequency inverters.

A recurring question from our clients is how high-frequency inverters differ from low-frequency inverters.

The main characteristics of low frequency (LF) inverters are:

• Simple structure
• Protections made at low voltage
• Has frequency transformer
• Operates with greater stability and robustness
• Can operate at higher peak power
• They have high tolerance to industrial loads
• They are more expensive, larger size, higher weight, slightly lower efficiency

The main characteristics of high frequency (HF) inverters are:

• Lower price, smaller size, less heavy, slightly higher efficiency
• They are not the best option for inductive loads (water pumps, air conditioning, refrigerators)

Rekoser manufactures high quality low frequency inverters and high frequency inverters. You can take a look here.
