Economic Vector Inverter

Single tube inverter is a device for motor speed regulation with single power tube, which is widely used in industrial fields.

Structural Features

Single tube inverters adopt discrete IGBT tubes to replace packaged integrated IGBT modules. For a typical single tube IGBT inverter, three groups of discrete IGBT tubes connected in parallel in the same direction are welded on the PCB board. Thermal conductive silicone grease is evenly coated on the other end of discrete IGBT tubes which are fixed on the radiator. Such structure cuts overall cost and facilitates replacement when single IGBT tube breaks down. The inverter also consists of shell power board main control board base rectifier components DC cooling fan and other parts. Independent radiator design upgrades heat dissipation efficiency and extends service life.

Working Principle

The working principle of single tube inverters is similar to general inverters. The rectifier circuit converts alternating current into direct current at first. Under the control of control circuit, discrete IGBT tubes inside the inverter circuit adopt high frequency switching technology to convert direct current into alternating current with adjustable frequency and voltage for motor power supply so as to realize motor speed regulation. The control circuit precisely controls the on off time of discrete IGBT tubes according to set parameters and feedback signals to complete frequency conversion and power adjustment.

Performance Features

Cost Advantage

The adoption of discrete IGBT tubes greatly reduces overall cost compared with inverters using integrated IGBT modules.

Compact Size

Simple structural design makes the single tube inverter occupy smaller installation space.

Easy Maintenance

Only the faulty single tube needs replacement once damaged instead of the whole integrated module, which lowers maintenance cost and operation difficulty.

Limited Power Range

Single tube inverters are not applicable for high power working conditions and are only available for low power operation generally.

Application Scenarios

Single tube inverters are largely applied in water pumps fans compressors and other equipment. They are also commonly used in low power small industrial equipment and civil electrical appliances including small ventilation fans household air conditioners. The product realizes precise speed and torque adjustment to save energy and optimize equipment operation performance.
