· The Difference between Forward Switching Power Supply and Flyback Switching Power Supply

As an indispensable component of modern electronic devices, switch mode power supplies are widely used in various fields. In the design of switching power supplies, forward and flyback are two common topology structures. This article will explore in detail the differences between forward and reverse switching power supplies, including their working principles, characteristics, and application scenarios.1.Working principleForward switching power supplyWhen the switching transistor is turned on in a forward switching power supply, the current passes through the primary winding of the transformer, transferring energy to the secondary winding, and then outputting DC power through rectification and filtering. When the switch is turned off, the secondary winding of the transformer continues to flow through a diode to maintain stable output voltage.Flyback switching power supplyWhen the switching tube of the flyback switching power supply is turned on, the primary winding of the transformer...

· The Difference between Switch Mode Power Supply and Linear Power Supply

In modern electronic devices, power plays a crucial role. Switching power supply and linear power supply are two common types of power supply, which have significant differences in working principle, efficiency, volume, voltage stability performance, and price. This article will explore these differences in detail through specific examples.Switching power supply linear power supply1. Working principleLinear power supply: Stabilize the output voltage by adjusting the conductivity of the transistor. The working principle of a linear power supply is relatively simple and direct, just like a faucet that can adjust the size of the water flow and adjust the output voltage as needed.Switching power supply: Using the conduction and turn off of switching tubes to control voltage conversion. Switching power supply is more like an intelligent water valve, quickly switching on and off to control water flow, thereby achieving efficient voltage conversion.2. EfficiencyLinear power supply: Due to th...

· How to choose a suitable switching power supply?

In modern electronic devices, switch mode power supplies play a crucial role as power supply devices. It converts mains power into stable DC power, providing reliable power for various electronic devices. However, there are various types of switching power supplies on the market, and how to choose the appropriate switching power supply has become a concern for many people. This article will provide a detailed introduction to the key points and considerations for selecting a suitable switching power supply. 1. Determine load demandFirstly, it is necessary to clarify the power requirements of the load equipment, including parameters such as voltage, current, and power. This information can be found in the device's specification manual or power label. Ensure that the output voltage and current of the selected switching power supply can meet the requirements of the load equipment, and leave a certain margin to avoid overload or underload situations.2. Stability and reliabilityThe stabi...

· How to improve power factor in switch mode power supplies?

The power factor of a switching power supply represents the ratio of output current to input voltage, which is a very important indicator. If the power factor is low, it will lead to more energy waste and affect network quality. Here are some methods to improve the power factor of switching power supplies: Adopting PFC technologyPFC (Power Factor Correction) technology is currently one of the most effective methods to improve the power factor of switching power supplies. Improve power factor by controlling the phase of input current. PFC technology can effectively improve the efficiency and power factor of switching power supplies.Reduce harmonic pollutionSwitching power supplies can generate many high-frequency harmonics during operation, which affects the normal operation of the power grid. To reduce this impact, measures such as filters and noise cancellers should be considered in the design of switching power supplies to reduce harmonic pollution.Choose the appropriate capacito...
