Suppliers of frequency converter supporting equipment remind you: rectification feedback unit is an important component of the frequency converter, the main role is to return the renewable energy generated by the motor to the power grid, to achieve the efficient use of energy.
The principle of the inverter rectifier feedback unit is that when the motor slows down or brakes, renewable energy is generated, which if not treated will cause the motor to overheat or damage. The rectifier feedback unit avoids waste of energy and damage to the equipment by converting this renewable energy into DC and feeding it back to the grid.
In practical applications, the rectification feedback unit is widely used in various motor systems that require frequent start-up, braking and speed adjustment, such as elevators, fans, water pumps, etc. For example, in elevator systems, when the elevator rises or falls, the motor needs constant speed adjustment to maintain smooth operation.
The design and optimization of the rectification feedback unit is important for improving the performance and stability of the inverter. With reasonable circuit design and control strategies, more efficient energy feedback, lower equipment losses and longer service life can be achieved. At the same time, the rectification feedback unit also needs to consider the compatibility and safety of the grid to ensure that the feedback current does not cause interference or harm to the grid.
In short, the rectification feedback unit is an integral part of the frequency converter. It can feed the renewable energy generated by the motor back to the grid, improve energy use efficiency, and protect the equipment from damage. Through reasonable design and optimization, the rectification feedback unit can provide stable, efficient and reliable operation guarantee for various motor systems.
