What is a power supply?

 

 

A power supply is a device or system that provides energy to electronic devices, functioning much like the human heart as a critical component in ensuring their normal operation. Its role is to supply current, voltage, and power to maintain the proper functioning of electronic devices.
 

The working principle of a power supply can be divided into two basic aspects: energy conversion and voltage regulation.
 

Firstly, the power supply converts input DC or AC electrical energy into the required form of DC or AC electrical energy through an energy converter. This process typically involves steps such as rectification, filtering, transformation, and flyback. Rectification converts alternating current into direct current, filtering removes high-frequency components from the current, transformation adjusts voltage, current, and frequency, and flyback enables regulation and control of electronic loads.
 

Secondly, the power supply adjusts output voltage and current through a voltage regulator to meet the various working requirements of electronic devices. This process includes basic functions such as voltage stabilization, regulation, protection, and feedback. Voltage stabilization maintains output voltage within a stable range, while regulation automatically adjusts voltage according to load changes, ensuring the safety and stability of the power supply. Feedback continuously monitors and controls the output voltage and current.
 

The main function of a power supply is to convert electrical energy into various forms to meet the needs of electronic products. It can convert alternating current into direct current and adjust voltage and current as required. Additionally, power supplies incorporate protection functions to prevent short circuits, overload, and overheating, ensuring safe equipment operation.
 

With the proliferation of electronic devices like computers, mobile phones, and appliances, power has become integral to daily life. Modern life relies heavily on electronic devices, each requiring specific power supplies; for instance, laptops need chargers, while smartphones use USB charging cables. Given this reliance, the quality of power significantly impacts device efficiency and lifespan. Thus, it's crucial to pay attention to power supply quality and choose suitable options to ensure equipment operates normally and has a prolonged lifespan.

Question: Inquire about the circumstances leading to the power supply damage and whether there have been any violations in its usage.

Measure: Before powering on, use a multimeter to measure the voltage at both ends of the high-voltage capacitor. If the fault is due to a failure of the switching power supply to oscillate or an open circuit in the switching tube, in most cases, the voltage at both ends of the high-voltage filtering capacitor will not discharge, and this voltage may exceed 300 volts. Exercise caution. Measure the forward and reverse resistance at both ends of the AC power line and the charging status of the capacitor using a multimeter. The resistance value should not be too low, as this may indicate a short circuit inside the power supply. Capacitors should be able to charge and discharge. Disconnect the load and measure the ground resistance of each group of output terminals. Normally, the meter needle should show capacitor charging and discharging oscillation, and the final reading should indicate the resistance value of the discharge resistor in the circuit.
