The essence of energy feedback is active inverter, and the realization method of energy feedback of general inverter is to feed renewable energy to the grid with an anti-parallel three-phase inverter at the uncontrolled rectification of the pre-stage of the general inverter. The main circuit of the energy feedback equipment is mainly composed of thyristors, IGBTs and IPM modules.

Hope Sunland Technology Co., Ltd. is a national key high-tech enterprise dedicated to the research and development of high, medium and low voltage frequency conversion technology and the design, development, production, sales and service of related products.

Motherboard faults are often manifested as faults that are difficult to visually identify, such as system startup failure and screen invisibility. You can use a brush to gently brush off the dust on the motherboard, in addition, some plug-in cards and chips on the motherboard are in the form of plugs.

Prior to the introduction of frequency converters, overhead crane operators operated the cranes using contactor-based controls. For low-cycle cranes, the system is equipped with a single or two-speed motor. For cranes with higher load cycles, they use so-called wound rotor motors. ...

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

In terms of power supply, everyone may know that the inverter and the inverter power supply are auxiliary equipment for charging electrical appliances, but many people do not know what is the inverter power supply and what is the inverter. With the continuous progress of the times, electrical appliances will be constantly updated, and auxiliary equipment is constantly changing.

The wiring of the inverter cabinet refers to the correct connection between the inverter and the motor, power supply and other equipment. The wiring requirements of the cabinet are carried out in accordance with the electrical principles and equipment specifications to ensure the normal operation and safety of the system. The following is the cabinet ...

For the most popular electrical control equipment inverter (Variable-frequency Drive, VFD), as a precision electronic industrial control equipment, in order to run smoothly for a long time, we, as professional and technical personnel, need to be on the VFD device or before the operation.

Soft starter is actually a motor control device with motor soft start, soft stop, light load energy saving and a variety of maintenance functions. First of all, it is a three-opposite parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. By manipulating the conduction of three opposite parallel thyristors ...

When we have selected a suitable Variable-frequency Drive (VFD), we also need to consider whether we need to equip other peripheral equipment according to the actual situation of the site.
