What Does Energy Feedback Intensity Mean?
1 Answers
Energy feedback intensity is a type of specialized braking unit for frequency converters, primarily used in high-inertia, drag-type variable frequency speed control systems. It helps the motor feed the regenerative electrical energy generated during deceleration back into the power grid while assisting the system in achieving rapid braking functionality. The role of energy feedback: Energy feedback automatically detects the DC bus voltage of the frequency converter, inverts the DC voltage of the converter's DC link into an AC voltage with the same frequency and phase as the grid voltage, and connects it to the AC grid after multiple noise filtering stages, thereby achieving the effect of feeding energy back into the grid. The amount of energy feedback: The electrical energy fed back into the grid reaches over 97% of the generated energy, effectively saving power.
