DC-DC Converters: PAH75D24-5033/PV Application Field and Working Principle

DC-DC Converters are electronic devices used to control the flow of electricity from a power source to a load. The PAH75D24-5033/PV is a type of DC-DC converter. It is specifically designed for photovoltaic applications. In this report, we will discuss the application fields and working principle of the PAH75D24-5033/PV.

Application Field

The PAH75D24-5033/PV is designed for use in photovoltaic systems. It is a DC-DC converter that converts direct current from photovoltaic cells to an adjustable output. The output can be regulated between 24 and 50 volts with a maximum power of 33 watts. This converter is primarily used for applications that require a reliable power supply, such as battery charging. It can also be used in various embedded systems to increase efficiency and reduce energy losses.

Advantages

The PAH75D24-5033/PV has several features that make it ideal for photovoltaic applications. Firstly, it has high efficiency, up to 96%. This means it can effectively convert solar energy into usable electricity. Secondly, it also has a wide input voltage range of 12 to 80 volts, making it suitable for use in PV systems with fluctuating solar radiation levels. Lastly, it has a wide operating temperature range of -40 to 85°C, making it suitable for use in extreme climates.

Working Principle

The PAH75D24-5033/PV is designed using a buck topology and a constant on-time control structure. With this design, the power switch is always turned on for a fixed period of time, allowing the required power to be transferred to the load. The converter then enters a low-power standby mode, allowing the converter to reduce power losses and increase efficiency. The overall regulated output voltage is determined by the average current feedback through an internal voltage divider. This allows for tight voltage regulation even in varying input voltage conditions. The voltage is then stabilized by an internal voltage feedback loop.

Conclusion

The PAH75D24-5033/PV is a DC-DC converter specifically designed for photovoltaic applications. It is reliable, efficient, and has a wide input and output voltage range. The converter has a buck topology with a constant on-time control structure, which allows for precise voltage regulation. Thanks to these features, the PAH75D24-5033/PV is ideal for various photovoltaic applications.
