Differences between power inverter and frequency inverterby RENDA ups power Marketing
There are a lot of people confuse the power inverter and the inverter, the difference between them other is still very large, then the difference between the power supply and the frequency inverter is mainly reflected in where?
Frequency power is constituted by the entire circuit AC DC converter means an exchange of a filter, variable frequency power supply is very close to the ideal of AC power, you can output the grid voltage and frequency of any country. DC by the AC inverter is an alternating current (modulated wave), and other circuits, the standard name for variable frequency drive inverter should be the inverter. The output voltage waveform is a square wave pulse, and more harmonic components, voltage and frequency while proportionally change, can not be adjusted separately, does not meet the requirements of the AC power supply.
Frequency Power: constant frequency during startup can provide clean, reliable, low harmonic distortion, stable voltage and high frequency sine wave power output, very close to the ideal of AC power.
Variable frequency drives: The drive is designed specifically for motor inverter startup, start voltage, frequency synchronization rises, with its modified power supply, electrical equipment may be affected, especially the variable frequency drive inverter, controlled rectifier, communications equipment.
Output voltage variable frequency power supply under full load conditions, the output voltage is set voltage of 1%, while the output frequency of the inverter as changing the motor operating characteristics changes. Power inverter no radiation interference, conduction interference low, to meet power requirements for laboratory equipment, while lower radiation interference of the inverter, conducted interference is strong.
