The invention discloses a current limiting control method of a rectifier bridge, which specifically includes the following steps: step 1: basic current detection, step 2: resistance regulation method, step 3: voltage regulation method, step 4: alternating current phase regulation method, step 5: The data after comparison shows that the present invention relates to the field of current limiting technology. In the rectifier bridge current limiting control method, the rectifier bridge circuit can effectively limit the current in the circuit through double adjustment of the input impedance and output impedance, effectively avoiding the sudden change of the current in the circuit, and improving the controllability of the circuit , through the setting of the phase control module, through the control of the AC phase in the rectifier bridge circuit, the voltage and current can be adjusted, and the specific conditions of the relevant phases in the circuit can be obtained effectively through phase feedback, which further improves the reliability of the circuit in use. Safety, so that the rectifier bridge circuit can fully control the input voltage in the circuit.

Description

technical field [0001] The invention relates to the technical field of current limiting, in particular to a current limiting control method for a rectifier bridge. Background technique [0002] The circuit is composed of power supply, electrical appliances (load), wires, switches and other components. When the circuit is turned on, it is called a path, and when it is turned off, it is called an open circuit. Only through the path, can the current flow through the circuit. A break in a circuit is called an open circuit or an open circuit. If there is no load between the positive and negative poles of the power supply in the circuit but it is directly connected, it is called a short circuit, and this situation is never allowed. Another kind of short circuit means that the two ends of a certain component are directly connected, and at this time, the current flows through the direct connection without passing through the component. This situation is called the short circuit o...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rectifier bridge current-limiting control method, which solves the problem that the internal current of an ordinary circuit should change within a certain range during operation, but in actual operation, it is often caused by a surge in voltage. The current changes too much, which will damage the electrical appliances. The traditional rectifier bridge can effectively change the current, but it cannot practically limit the current size.
