Troubleshooting of SMPS power adapter

Posted by FCWTechnologies on December 14th, 2020

Switching transistors consumes much less heat with greater efficiency with the FCW adaptor. SMPS can fail and produce a very high output voltage which destroys the instrument. A broken PC can cause the PC to either restart automatically or shut down immediately. Confirm the SMPS complaint as follows:

• Confirm if the power cord in the socket of the SMPS is tight and well connected to the UPS.
• Remove the 4 pin connector and connect the 10 ohm 10 watt resistor to the yellow (+ 12V) and black (glue) pins of the connector.
• Connect the power code to the UPS and the 24 pin cord to the motherboard.
• Using short wire shorten pin 16 (green) with adjacent black pin (pin 17).
• If the fan is running normally, the SMPS is working normally.
• If not, unplug the fan and test it with a 12 volt supply. If the fan is OK, check the voltage at the output pin of the connector.

Advantages and disadvantages

The main advantage of SMPS is higher efficiency than linear regulators because the switching transistor dissolves less power when acting as a switch with the FCW adapter price. The SMPS is a smaller size and lighter in weight than heavy line frequency transformers and similar heat constructions. Additional power losses are often lower than transformers.

The disadvantages of SMPS are better complexity, high-amplitude generation; high frequency energy dissipation which must block LPF to avoid LPI (electromagnetic interference), harmonic frequencies and ripple voltage at switching frequencies.Low cost SMPS Electrical switching can add noise to the main power line, causing interference to connected devices in the same phase. Non-power factor Improved power supply is also a source of synchronous distortion.

Linear controlled power supply

Everyday electronic devices, especially those with integrated circuits, need a reliable DC voltage source that can provide power at all times without any swings. In this blog, we will focus on two power supply design topologies for your next project, linear control and power supply replacement consideration. The power supply you ultimately choose depends on your requirements for efficiency, location, output regulation, transient response time, and cost.

Linear regulators were the preferred power supply for electronic devices until the 1970s to convert alternative devices (AC) to static direct current (DC). Although this type of power supply is not practiced today, it is still the best option for applications that require minimal noise and ripples.
