Circuit to prevent reverse power supply
The following are a few types of circuits to prevent reverse power supply: 1. ** Diode-proof reverse connection circuit **: A single circuit is connected in series to the power supply input end. By using the one-way conductivity of the circuit, it can conduct in the forward direction and cut off in the reverse direction. When the power supply was reversed, the LED would not conduct, thus avoiding reverse power supply. However, during normal operation, a voltage drop of 0.7V will occur on the LED, which is not suitable for circuits with strict requirements on the supply voltage. 2. ** Fuse + Parallel Diode **: The principle is also based on the one-way conductivity of the Diode. When the power supply is connected normally, the LED does not work, and the current flows into the circuit through the fuse. After the power supply is connected in reverse, the LED is instantly turned on, causing the positive and negative poles of the power supply to be short-circuited. The short-circuit current generated by the short-circuit fuses the fuse, achieving the effect of reverse connection protection. However, the fuse selection must be compatible with the circuit characteristics. 3. ** Full-bridge Rectifiers Anti-reverse Connection Circuit **: No matter what the input power is, the output is always fixed, so it can work regardless of the positive and negative connection circuit. However, when it works, the full-bridge rectify will produce a voltage drop of about 1.5V. 4. ** Low internal resistance of the anti-reverse connection circuit of the upheaval protector **: When the power supply is normally connected, the upheaval protector is turned on. After the power supply is reversed, the upheaval protector is turned off to achieve reverse connection protection. Due to factors such as the improvement of the process technology, the internal resistance of the semiconductor was extremely small, and the impact on the voltage drop and power consumption of the circuit was minimal.

eps power supply reverse transmission
The EPS reverse transmission technology allows excess power to be fed back to the grid when the equipment decelerates or stops. This process realized energy recovery. When applied in high-energy-consuming industrial fields (such as elevators, cranes, and other equipment that frequently started and stopped), it could significantly reduce energy consumption, reduce the overall load on the power grid, reduce mechanical wear, and extend the service life of the equipment. From the perspective of environmental protection, through the application of EPS reverse transmission technology, the production demand for additional energy was reduced, thereby indirectly reducing the amount of fossil fuel burned, helping to reduce the carbon footprint and combat climate change. It also increased the feasibility and attractiveness of regenerative energy and promoted the development of green energy. In terms of economic benefits, after a household or enterprise uses EPS reverse transmission, it can reduce the amount of electricity purchased from the grid, thereby saving electricity bills, especially for users with large power consumption. In industrial applications, it can improve the stability and reliability of the power system and reduce the power shortage caused by sudden power demand peaks. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Working Principle of Reverse Connection Control Circuit of Three-phase Induction Machine
The working principle of the three-phase induction motor reverse connection control circuit is as follows: 1. Reverse braking was completed with the help of the speed relay SD. There was a heavy object in the speed relay mechanically connected to the motor shaft. 2. After pressing the start button, the motor of the SSB1 rotated to a certain speed. Due to the inertia, the weight pressed the speed relay micro-switch to send a signal, and the SD contact was connected. 3. When the stop button SSB0 is pressed, the KM1 loses power, and the motor enters the free parking state instantly after being disconnected from the power supply; after the normally closed contact of the KM1 recovers, the KM2 is energized, and the motor enters the braking state after being connected with the reverse power supply; when the speed of the motor drops and is lower than the speed at which the speed relay contacts are pressed together, the speed relay micro switch is disconnected, and the motor enters the free parking state again until it completely stops. 4. For KM1 and KM2, AC contactors with mechanical interlocks shall be selected, and their normally closed contacts shall be set with electrical interlocks to ensure safety. 5. Circuit breakers QF1 and QF2 are used for short-circuit protection, and thermal relay KH is used for long-term overload protection of the motor. 6.
