Low Power Input 220V Single Phase Output 220V 3Phase AC Vector VFD Variable Frequency Drive
A low-power input 220V single-phase to 220V three-phase AC vector variable frequency drive (VFD) is a device that converts single-phase AC power into three-phase AC power and can adjust the output frequency and voltage. It is suitable for driving three-phase AC motors, particularly in scenarios where three-phase power is unavailable but three-phase motors are required. Below is a detailed explanation covering its technical principles, product features, selection recommendations, application scenarios, and precautions.
I. Technical Principles
Rectification Stage : Converts single-phase 220V AC power into DC power through a rectifier bridge.
Filtering Stage : Uses capacitors or inductors to filter the DC power, obtaining a stable DC voltage.
Inversion Stage : Utilizes power devices such as IGBTs (Insulated Gate Bipolar Transistors) to convert the DC power into three-phase 220V AC power, controlling the output voltage and frequency through PWM (Pulse Width Modulation) technology.
Vector Control : Achieves precise control of motor torque and speed by decoupling the torque and flux components of the motor current.
II. Product Features
Wide Input Voltage Range : Supports input voltage fluctuations of ±15% or ±20% around single-phase 220V, adapting to different grid environments.
Adjustable Output Voltage : The output three-phase voltage can be adjusted within the range of 0-220V to meet the needs of different motors.
Wide Frequency Adjustment Range : The output frequency range typically spans from 0-400Hz or 0-600Hz, enabling stepless speed regulation of motors.
Vector Control Technology : Provides high starting torque (e.g., 150% or 180% of rated torque at 0.5Hz), a wide speed regulation range (1:100 or 1:1000), and high speed control accuracy (±0.5% or ±0.02%).
Comprehensive Protection Functions : Equipped with protection features against overcurrent, short circuits, overtemperature, overvoltage, and undervoltage to ensure safe operation.
User-Friendly Operation : Features a digital display panel and multifunctional input terminals, supporting parameter copying and remote monitoring.
III. Selection Recommendations
Power Matching : The rated power of the VFD should be at least 1.5 times that of the motor. For example, when driving a 1kW motor, a VFD with a minimum power of 1.5kW should be selected. If the load is heavy (e.g., gear pumps, hydraulic pumps) or there are stall conditions, a VFD with at least twice the motor power should be chosen.
Voltage and Frequency Range : Ensure that the input voltage range, output voltage range, and output frequency range of the VFD meet the application requirements.
Control Mode : Select the appropriate control mode based on application needs: V/F control for simple speed regulation scenarios, non-PG vector control (SVC) for moderate performance requirements, or PG vector control (FVC) for applications demanding high starting torque and precise speed control.
IV. Application Scenarios
Small Mechanical Equipment : Such as small CNC machine tools, woodworking machinery, and textile machinery, which typically require three-phase motor drives but may only have single-phase power available on-site.
Pumps and Fans : Such as water pumps and fans, where precise control of flow and air volume can be achieved through variable frequency speed regulation, resulting in significant energy savings.
Household and Commercial Equipment : Such as elevators and automatic doors, which have high requirements for starting torque and speed control accuracy.
