Frequency Converter Power Supply and Frequency Converter

Frequency conversion power supply is a frequency conversion device consisting of AC direct current and AC filter, which has been widely used. Frequency conversion power supply can not only simulate the output of power grid indicators in different countries, but also provide pure and reliable, low harmonic distortion, high stable voltage and frequency sinusoidal power supply output for export electrical appliance manufacturers in design, development, production, detection and other applications. Frequency conversion power supply is very close to the ideal AC power supply, which can output the grid voltage and frequency of any country. Frequency converter is composed of AC direct current and AC (modulation wave) circuit. The standard name of frequency converter should be frequency converter. Its output voltage waveform is pulse square wave, and has many harmonic components. Voltage and frequency change proportionally at the same time. It can not be adjusted separately, which does not meet the requirements of AC power supply.

Reliability 
Frequency conversion power supply: the overall design of power supply, after years of 

technical accumulation, to ensure the stable and reliable operation of power supply.          
Frequency Converter: The shore power supply assembled by frequency converter is relatively simple to produce. Because the main part of frequency converter is purchased, it is difficult to ensure that the parameters of frequency converter match those of other components.

Secondary security
Frequency conversion power supply: the frequency is constant during start-up. It can provide pure, reliable, low harmonic distortion, high stable voltage and frequency sinusoidal power output, very close to the ideal AC power supply.

Frequency Converter: The design of frequency converter is specially for motor starting with frequency conversion. When starting, the voltage and frequency rise synchronously. The power supply modified with frequency converter may affect the electrical equipment, especially the frequency converter, controllable rectifier and communication equipment.

Three-phase unbalance
Frequency Conversion Power Supply: The inverters adopt star mode, each phase can be loaded independently, adapting to three-phase completely unbalanced load. The unbalance can be less than 3%.

Frequency Converter: Frequency Converter adopts Delta Inverter. Although the output is transformed into Y-type output through transformer, it has poor adaptability to three-phase unbalanced load, which may increase the reverse torque in motor, increase the temperature, decrease the efficiency, increase energy consumption, vibration and output loss.

after-sales
Frequency Conversion Power Supply: The manufacturer develops and produces its own power supply. It is very familiar with the power supply. Once there is a problem, it will solve the problem in the shortest time at the power supply site

Frequency Converter: Because most of the converters are purchased from other manufacturers specializing in the production of converters, once problems arise, power manufacturers will remove the converters and send them back to the converter manufacturers (part of which is abroad) for a long maintenance period, and the converter manufacturers will not be responsible for matching the converters with transformers and LC low-pass filter circuits. Even on-site maintenance is difficult to ensure a thorough solution to the problem.
