Three-phase inverter power supply is a high-performance precision power supply equipment, which is capable of transforming the existing AC grid current into a stable and pure sine wave power supply of the required frequency.
This kind of power supply equipment is widely used in home appliance manufacturing, motor, electronic manufacturing, IT industry, computer equipment manufacturing, laboratory and test units, aviation, military units, medical equipment, railroads, oil drilling platforms and other fields, for the provision of different electric power and special requirements of the place required power.
I.Working Principle
The working principle of three-phase inverter power supply is to convert the input three-phase AC power supply into DC power through rectifier circuit, then smooth the fluctuation of DC power through filter circuit, and finally convert DC power into high frequency AC power through inverter circuit.
The inverter circuit is the core part to control the frequency and voltage, which is usually realized by using modulation techniques such as SPWM (Sinusoidal Pulse Width Modulation) or MPWM (Modulated Pulse Width Modulation Technique).
Ultimately, the voltage is raised or lowered by a transformer to output a three-phase AC power supply with adjustable frequency and voltage.
