The three-phase variable frequency power supply is fabricated by MPWM mode. The active component IGBT module is designed to make the capacity of the machine up to 200KVA, to isolate the transformer input and output, to increase the stability of the whole machine, especially for inductive, capacitive and special loads, load testing and Life test reliability is high. There are two main types of three-phase variable frequency power supply: transistor amplifying three-phase variable frequency power supply and PWM switching type three-phase variable frequency power supply. DP series three-phase variable frequency power supply, with microprocessor as the core, PWM method, sinusoidal pulse width modulation and other technologies, so that the single unit capacity can reach 1000KVA, to isolate the transformer output to increase the stability of the whole machine, with strong load adaptability, The output waveform has good quality, good operation waveform, simple operation, small size and light weight. It has short-circuit, over-current, over-voltage, over-heating and other protection functions to ensure reliable operation of the power supply.
