When using a voltage regulator, we need to pay attention to the following aspects. Firstly, it needs to be reversed in the circuit to stabilize the voltage. That is to say, the negative pole of the voltage regulator is connected to the high potential in the circuit, and the positive pole is connected to the ground potential. If it is reversed, it will burn out the voltage regulator due to excessive current.
Silicon carbide is an inorganic substance with the chemical formula SiC. It is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt needs to be added when producing green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite.
TVS (Transient Voltage Suppressor) tube, also known as Transient Voltage Suppressor diode, is a new type of high-efficiency circuit protection component invented on the basis of Zener diode technology. The core advantages of TVS tube are p-second response time and high surge absorption ability.
The reasons for the inconsistent voltage drop of the four diodes in the rectifier bridge may be the following:
The diode mode is mainly used to measure the forward voltage drop of the diode, while the buzzer mode, also known as the on/off mode, is mainly used to measure the continuity of the circuit. Some multimeters combine the buzzer mode with the diode mode, while others separate these two modes.
A rectifier bridge typically consists of four electrodes, two of which are positive (Anode, marked as AC,~or arrow) and the other two are negative (Cathode, marked as -, - or circle).
