· Several overcurrent protection methods in power modules

With the widespread application of modular power supplies in various electronic devices, it is inevitable that overcurrent, overvoltage, or short circuit phenomena may occur due to other factors during use. In order to protect product performance, modular power supplies are designed with overcurrent and short circuit protection functions. Below are several methods of overcurrent protection.AC DC POWER MODULEFirst type: rated current droop typeHiccup style, self-healing. The principle is to check the circuit to see if there is any overcurrent, and then provide feedback to the control circuit to turn off the output. If overcurrent is still detected after a certain period of time, then provide feedback to the control until the overcurrent disappears.Second type: constant current typeThe product maintains a constant current value, and since the current value is larger than the full load, the design power margin needs to be larger than the nominal value.Third type: constant power typeWhen...

· The difference between active components and passive components

Active components Active components refer to electronic components that can control the magnitude of current and voltage, and they require external power or signals to operate. Common active components include transistors, field-effect transistors, integrated circuits, etc. Active components have functions such as amplification and switching, which can effectively control and adjust current or voltage.Active components are widely used in electronic products, such as computers, mobile phones, audio systems, etc., and can achieve various functions such as signal amplification and logical operations.Passive components Passive components refer to electronic components that cannot control the magnitude of current and voltage. Passive components generally have certain characteristics such as resistance, capacitance, inductance, etc., such as resistors, capacitors, inductors, etc. Passive components are mainly used for circuit connections, energy storage, filtering, and cannot acti...

· How to extend the service lifespan of portable power source?

Frequently traveling for too long and not charging your phone in a timely manner, this is when an indispensable travel companion - mobile power, commonly known as "power bank" - appears. In this modern era, mobile power has become one of the indispensable main electronic products. People who frequently use mobile power know that mobile power has a lifespan, and long-term consumption of mobile power can easily lead to damage. So, is there any way to extend the lifespan of the portable power source we usually purchase? Here are some tips from the editor, hoping to be helpful to everyone.Be sure to pay attention to the charging frequency when using a mobile power source and avoid excessive charging. Some people use a mobile power source to start charging after just using a little electricity, and then start charging again after using a little electricity. This method is not advisable, and the charging frequency of the power bank should not be too high. Tip: It is best to recharge when th...

· The reasons why LED power supplies require high efficiency

LED power supply is a type of power supply, also known as a power supply unit, which provides the electrical energy required for LED lighting. Due to the characteristics of LED beads, they can only be driven by direct current. Therefore, an integrated circuit is needed between the mains power (AC power) and the LED to convert AC power into DC power. This integrated circuit is the LED control drive. So what is the reason why LED power supplies require high efficiency?LED constant voltage waterproof power supplyThe reason why LED power supplies require high efficiency:1. The first reason is that it can save energy;2. The high efficiency of LED power supply can reduce power loss. For example, an LED power supply with an output power of 150W can achieve a loss of 7.9W when the efficiency reaches 95%, and 26.5W when the efficiency is only 85%;3. Efficient power supplies can extend their lifespan and significantly improve reliability;4. If LED power supply can achieve high efficiency, it ca...

· The difference between switch mode power supply and power supply unit

Switch mode power supplies and power supply units are a concept in the minds of many people, but they are actually different. Below is a detailed introduction to their differences:600W Switching Power Supply1. Different working principlesA switching power supply is an electrical appliance that converts high voltage into low voltage, and the most important part of it is the switching power supply chip. The switching power supply chip is the core component of the power converter, which can achieve power conversion by continuously switching the state of the switching transistor. A power supply unit, also known as an adapter, is a device that converts alternating current into direct current, providing power to electronic devices.2. Different application scenariosThe application scenarios of switch mode power supplies and power supply units are also different. Power supply unit is suitable for some low-power appliances, such as mobile phone chargers, laptop adapters, etc. These devices req...
