The inverter power supply used for converting AC to DC→AC conversion is known as a frequency converter inverter. Unlike the variable frequency drive used for motor speed control, it primarily functions to convert existing AC power into a stable pure DC power of the desired frequency. An ideal AC power source is characterized by stable frequency, voltage, zero internal resistance, and a pure sine wave voltage waveform (free from distortion). As frequency conversion drives are very close to ideal AC power sources, the use of frequency converters in industrialized countries/regions can provide a better power supply environment for electrical equipment, and objectively evaluate the technical performance of electrical equipment. They are increasingly being used as standard power sources. Frequency converter power supplies mainly come in two types: linear amplifier type and PWM switch type.Aviation Power
The HY series programmable variable frequency power supplies are developed using the MPWM mode, with IGBT modules at the core and microprocessors as the central processing unit. They utilize digital frequency division, analog-to-digital conversion, instantaneous value feedback, and sine pulse width modulation techniques. With output via an isolation transformer, they can produce a single capacity of up to 100 kVA, thereby enhancing the stability of general machinery, offering strong load adaptability, excellent output waveform quality, ease of operation, compact size, and lightweight. They are equipped with protection functions for short circuits, overcurrent, overload, and overheating, ensuring reliable operation of the power supply.400Hz Power Supply
