The Difference between Standard Regen and Low Harmonic Drives

There can be some confusion about inverter types – standard / 6-pulse, low harmonic, or regen drives. In this article, we explain the differences with their pros and cons. 6-Pulse Drives These are the most common type of inverter and they have a diode rectifier on the input. Advantages: Relatively cost effective Compact Efficient (around 98%) Readily available Disadvantages: Generates harmonics on the mains, especially those without a dc or ac choke Wastes energy when…
