Now due to the continuous improvement of electronic technology, the power supply also has great requirements, that is, to be able to meet the requirements of the load and there is a need to provide continuous and stable power, in general, we are required to provide stable DC power, so, with the DC regulated power supply, it occupies a very important position in the whole power supply technology. Therefore, we must first know the composition of the DC regulated power supply, fully understand the DC regulated power supply, so that we can better learn the power supply technology.
(1) Power transformer: This is a kind of soft magnetic electromagnetic components, its function is to carry out power transmission voltage transformation and insulation isolation, power transformer in power technology has played a very wide range of applications.
(2) Rectifier circuit: The function of the rectifier circuit is to convert alternating current into direct current. Generally, the rectifier circuit is composed of a transformer, a rectifier main circuit and a filter. It has a wide range of applications in the field of DC motor excitation adjustment plating.
(3) filter circuit: filter circuit is able to filter out the rectifier output voltage ripple. It is composed of reactance components, such as parallel capacitors at both ends of the load resistance, and a compound filter circuit composed of inductors and capacitors.
(4) voltage regulator circuit: voltage regulator circuit is the voltage, load, ambient temperature, circuit parameters changes can still provide a stable constant voltage circuit, such DC regulated power supply is now used by most of the electronic equipment.
