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.

What is the solution for unstable car throttle?

Car throttle unstable solution is: adjust the action of stepping on the throttle pedal, when stepping on the throttle pedal, let the heel of the right foot rest on the floor of the cab as a support point, place the sole on the throttle pedal, and use the flexion and extension of the ankle joint to press down and lift the throttle pedal. The throttle, also known as the air valve and throttle valve, is a control device that regulates the engine's power thrust. It controls the opening of the carburetor's throttle valve to regulate the cylinder's filling amount, determining the engine's output power. Precautions for stepping on the throttle are: 1. Be gentle when pressing and releasing the throttle pedal, achieving a light press and slow lift; 2. The release of the clutch should be closely coordinated with stepping on the throttle, with agile movements; 3. Choose the appropriate gear to keep the engine running at medium speed and larger throttle opening most of the time to save fuel; 4. Before the car moves or stalls, first release the throttle pedal and avoid suddenly revving the engine in neutral.
