DC Frequency Converter VFD Single to Three Phase

In remote areas, mobile platforms, or new energy systems, stable and reliable three-phase AC power sources are often scarce, but efficient three-phase motors are the best choice for power equipment. The SPX factory's high quality DC Frequency Converter VFD Single to Three Phase cleverly integrates the convenience of DC power supply with the superiority of three-phase motors. It not only makes it possible for DC sources such as solar panels and battery packs to directly "talk" to standard industrial motors, but also through intelligent control, enables every DC energy to be accurately and efficiently converted into controllable mechanical power.

Features:

Native support for DC input (such as 24VDC, 48VDC, 220VDC) eliminates the multiple conversion steps of "DC → AC → frequency conversion" in traditional products, and improves the overall efficiency of the system by 5% -15%, making energy utilization more direct and efficient.
Only a set of DC power sources (such as a battery or a string of photovoltaic panels) is needed to drive a standard three-phase motor, completely eliminating dependence on complex three-phase AC power grids and providing an extremely simplified power architecture for vehicles, ships, and independent equipment.
Output high-quality, low harmonic three-phase sine wave AC power, DC Frequency Converter VFD Single to Three Phase provides perfect driving power for standard three-phase asynchronous or synchronous motors, achieving smooth and stepless speed regulation from zero speed to rated speed.
Integrate electronic overload, short circuit, and phase loss protection, and limit the starting current to a very small range through variable frequency soft start, protecting the fragile DC power supply from impact and extending the life of the motor and mechanical system.
Design to adapt to the voltage variation range of the battery (such as the floating charging voltage range of lead-acid batteries), ensuring stable operation during power supply voltage fluctuations.
The CE-certified DC Frequency Converter VFD Single to Three Phase can automatically adjust the output power or enter standby mode based on the voltage level of the DC bus (reflecting the battery level), protecting the power supply from over discharge.

Working Principle:

DC power input → DC-DC voltage regulation and boost (if required) → DC bus voltage regulation → three-phase IGBT inverter bridge (controlled by microprocessor) → output adjustable frequency and voltage three-phase AC power.

Application

Drive solar deep well pumps, three-phase water pumps for off grid households, or small processing equipment to achieve direct utilization of clean energy.
DC Frequency Converter VFD Single to Three Phase utilizes the battery of vehicles/ships to drive three-phase motor equipment such as air conditioning compressors, hydraulic oil pumps, ventilation fans, etc.
Provide flexible power for three-phase auxiliary equipment on mobile communication vehicles, field work platforms, and electric agricultural machinery. Using a DC power cabinet in the laboratory, the DC Frequency Converter VFD Single to Three Phase supplies power to teaching demonstration equipment and R&D testing benches that require three-phase variable frequency speed regulation.
