Rectifier in use when the advantages and disadvantages
      Rectifier is a way to accelerate the heat dissipation of the heating device, weigh the advantages and disadvantages of a radiator has two points: cooling and quiet. A large number of integrated circuits are used in computer components. As we all know, high temperature is the enemy of integrated circuits. High temperature will not only lead to instability in the system, the use of life shrinkage, and even some of the parts will be abandoned. Resulting in high temperature heat is not from the computer, but the computer inside, probably said to be integrated within the circuit. The role of the Rectifier is to absorb these heat, and then spread to the chassis probably outside the chassis, to ensure that the normal temperature of the computer parts. Most of the radiator and heat components through the appearance of the war, absorb heat, and then through the various means to heat the notification to the distance, such as the atmosphere inside the chassis, and then the chassis will be sent to the chassis of these hot atmosphere, the completion of computer cooling.
 Universal Rectifier is an automatic switching element with isolation function, widely used in remote control, telemetry, communication, automatic control, electromechanical integration and power electronic equipment, is one of the most important control components.
Rectifier
General-purpose Rectifiers generally have a sensing mechanism (input section) that can reflect a certain input variable (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.) (Output section) between the input section and the output section of the Rectifier, and an intermediate mechanism (driving section) for coupling and isolating the input amount, the function processing and driving the output section.
Can the Rectifier work in a magnetic field?
For electromagnetic interference or radio frequency interference is more sensitive around the device, it is best not to use AC Rectifier Rectifier. DC Rectifier to use with a coil transient suppression circuit products. Those with solid-state devices or circuits to provide incentives and sensitive to the spikes Place, but also choose to have transient suppression circuit products.
Rectifier according to the type of load power can be divided into AC and DC type. According to the switch type can be divided into normally open and normally closed type. According to the isolation type can be divided into mixed type, transformer isolation type and photoelectric isolation type, with photoelectric isolation type is the most.

Rectifier is a new non-contact switching device, its components are solid-state electronic components. It uses the electronic components (such as switching transistor, triac and other semiconductor devices) switching characteristics, can be achieved without contact without spark to open and disconnect the circuit, and therefore known as "non-contact switch" It came out in the 1970s, because of its non-contact work characteristics, so that in many areas of electronic control and computer control has been increasingly widely used.
Rectifier according to the use of occasions can be divided into two types of AC and DC, they are in the AC or DC power supply load switch, can not mix below the AC Rectifier as an example to illustrate its working principle, Figure 1 is its (A and B) and two output terminals (C and D), is a four-terminal (A and B), and the two Rectifiers have two input terminals (A and B) and two output terminals (C and D) Device. Work as long as the A, B with a certain control signal, you can control the C, D between the ends of the "pass" and "off" to achieve "switch" function, in which the coupling circuit function is A, The B-side input control signal provides a channel between the input / output terminals, but electrically disconnects the (electrical) connection between the input and output terminals of the Rectifier to prevent the output from affecting the input, the coupling circuit The input element is "optocoupler", it is sensitive, high response speed, high input / output insulation (voltage) level; because the input load is light-emitting diodes, which makes the input of the Rectifier is easy to do With the input signal level match, in the use can be directly connected with the computer output interface, that is, "1" and "0" logic level control.
