PM-05-24

AC-DC converters are an important electronic component which are widely used in applications ranging from low-power consumer electronics to high-power industrial applications. The PM-05-24 is a type of AC-DC converter specially designed for switching power supply applications such as computers, TVs, air conditioners and so on. It uses synchronous rectification technology to convert AC mains input to DC output efficiently and reliably.

Features

The PM-05-24 converter features excellent power management performance, wide input voltage range (85-264VAC), input frequency range (47-63Hz), high power factor (> 0.9) and low output ripple (less than 100mV rms). In addition, it has integrated short circuit protection, overvoltage protection, overcurrent protection and over temperature protection.

The PM-05-24 also provides long-term reliability and is characterized by high temperature tolerance, wide operating temperature range, low component count and high system efficiency.

Applications

The PM-05-24 is suitable for various applications where stable DC power is required. Its wide input voltage range and high power factor make it particularly suitable for applications such as smart TVs, computers, air conditioners, home appliances, lighting systems, and medical systems. It can also be used in industrial power supplies, communications equipment, and various embedded control systems.

Working Principle

The PM-05-24 converter is a synchronous rectifier, which uses the principle of synchronous rectification to convert the AC mains to a DC output. Synchronous rectification is based on the fact that a device conducting current in both directions is less lossy than one conducting current in only one direction. In practice, a switch is used to control the direction of current flow, and the direction of current flow is synced with the phase of the input AC waveform. This allows a more efficient conversion with less losses.

The PM-05-24 uses a full bridge rectifier composed of four switching devices (MOSFETs) to control the direction of current flow. It also has two additional control circuits for each bridge. One is for controlling the on/off time of the switching device, and the other is for controlling the current conducting direction. The output voltage of the converter depends on the switching frequency and the DC bias voltage of the bridge.

Conclusion

The PM-05-24 is a high performance AC-DC converter specifically designed for switching power supplies applications. Its wide input voltage range, high power factor and low output ripple make it ideal for applications such as smart TVs, computers, air conditioners, home appliances, lighting systems, and medical systems. Its synchronous rectification technology also makes it efficient and reliable.
