Working Principle and circuit diagram of switching power supply

The working principle of the switch power supply in this paper is the analysis of the principle of the switch power supply engineers of Electronic enthusiasts. Based on the analysis of a wide range of switch power supply cases, this paper introduces the single-positive excited switch power supply and Self-excited switch power supply, push-pull switch power supply, Buck switch power supply, boost switch power supply and reverse switch power supply.With the world's attention to energy problems, th

Circuit diagram of wideband ALC amplifier with TL026 and other components

anything other than 1, we would has to adjust the resistances in bothAnother limitation of this amplifier design was the fact that its input impedances be rather low compared to that of some Other Op-amp configurations, most notably the noninverting (single-ended input) amplifier. Each of the input voltage source has through a resistance, which constitutes far less impedance than the bare in Put of an op-amp alone. The solution to this problem, fortunately, was quite

Circuit Diagram symbol

From: Circuit Diagram symbols are represented by a painting or calligraphy image.The symbols of electronic components (such as capacitors, resistors, diodes, three-pole functions, and integrated circuits). With the circuit diagram symbols, I can learn, dem

due to external jitter in practical application, we have adopted a design method to take its smooth transition data in several data inter-segment points when we data processing. The MCU finally selects the processing result output mode through the jumper. The System program flowchart is shown.At present, most devices do not have a simple direction recognition function. For more complex, higher-grade equipment, the use of positioning equipment is stro
