“ Power supply & throughout; This may be a general word. Staying at a hotel on a business trip, can't find the 220 v ac socket, you might say this hotel does not provide & other Power supply & throughout; 。 In this context, & other; Power supply & throughout; Means can be used in a power supply at the input of equipment & other; Ac input power & throughout; 。 Traveling, you find your notebook without & other; The power adapter & throughout; , you also will get used to say, with the computer, but didn't bring & other; Power supply & throughout; 。 If someone asks what is your occupation, do you think & other; Power supply & throughout; Answer or do & other; Switching power supply & throughout; , the other party may suddenly feel your career is very general, not a high-tech. And a high-tech power in your heart, because you are doing is a high-end power, high-end domestic no one has been able to do it, and the one who ask you, his head & other; Power supply & throughout; Only the 220 v alternating current (ac) on the wall, or a switch on the wall. You are not on a channel. Power seems to be too ordinary, because it is everywhere. Broad, as long as it can provide electricity equipment and facilities are power. In a narrow sense said, do the power of the power supply is switching power supply. I want to talk about is switching power supply. I have no search to find the official definition of switch power supply. In my understanding, switching power supply is done by the opening of the switch tube and shut off the electrical energy transformation. Electrical energy transformation includes: 1, AC/DC. Communication transform into dc, usually will be from the grid, two phase alternating current (ac) or 380 v, 220 v, three-phase alternating current into direct current. Low power AC/DC AC input is 220 v, high-power AC input is 380 v. According to the application field, different occasions, also known as AC/DC converter, rectifier, a power supply, communication power supply, power adapter, lighting power supply, etc. 2,DC / DC。 For DC DC transform, such as converting high voltage, low current, low voltage, high current according to the application field, different occasions, may be called the DC/DC converter, secondary power supply, power supply module, plate on the power supply, etc. 3、DC / AC。 Dc transform into communication, according to different application, occasion, may be called UPS, inverter, grid inverter, motor controller, etc. 4,AC/AC。 Communication transform into communication, product form, usually a frequency converter, used for motor control. In AC/DC, DC/DC corresponding to the two direction of industry market, industry insiders call & other; Switching power supply & throughout; , there is a specific industry high-end a power supply ( Also known as the communication power supply, but the meaning of communication power supply seems to be more widely) , generally refers to the telecom room 48 v power supply, the secondary power supply, custom power supply, power supply, computer power supply, laptop etc all kinds of electrical equipment, power adapter, cell phone charger power supply, rechargeable power supply, car charger, OBC,车载充电器) On-board DC/DC converter, lighting power supply ( Can divide again for the LED power supply, electronic ballast, HID power supply) , etc. Which corresponds to the DC/AC, AC/AC industry market, people usually say it do UPS, pv ( According to the photovoltaic panels direct current into alternating current (ac)) , do energy storage, frequency converter, motor controller. Organization of data from the network.
