AC DC ConvertersDC power generated from an AC power source is one of the most widely used form of energy conversion in the modern age. The use of AC DC converters is ubiquitous in industry and nationwide infrastructure. One type of AC DC converter that has seen significant popularity for such applications is the PBA100F-3R3-TN. This application field paper aims to illustrate how this device works and the fields of application for which it is most suitable.The PBA100F-3R3-TN utilizes a voltage transfer process for energy conversion, wherein an AC power source is stepped down through a transformer to provide the necessary voltage for the device to function. In essence, the AC waveform passes through an input filter which separates the DC and AC components of the waveform, before being transferred to the converter’s internal DC/DC converter via a transformer. This transformer contains two separate parts, a main transformer and a feedback transformer. The main transformer steps down the AC voltage into DC form, and the feedback transformer senses the DC voltage and provides the necessary feedback to the internal DC/DC converter.The internal DC/DC converter of the PBA100F-3R3-TN is what is responsible for the voltage transfer process and what sets it apart from other AC DC converters. It comprises of a Full-Bridge Rectifier, an output filter, and a Buck/Boost regulator. The rectifier is what converts the incoming AC voltage from the input filter into DC form. The rectified DC voltage is then passed through the output filter which removes any unwanted AC components and provides a clean DC output. This output is then sent to the Buck/Boost converter, which is what provides the voltage conversion process for the device.The Buck/Boost converter is a type of integrated switching circuit which allows the output voltage of the device to be either increased or decreased depending on the desired output voltage. This is achieved via the Buck/Boost regulator, which operates by constantly reprogramming the input voltages to the device to maintain the desired output voltage. This makes the device incredibly versatile and allows for a wide variety of outputs with a minimal amount of input power.Due to the versatility of this device, it is widely used for a variety of different applications. Most commonly, it is used in general-purpose DC/DC power converters, power supplies, and on-board power systems in the vehicle industry. It is also used as an energy harvesting solution, which allows for the efficient conversion of renewable energy sources, such as wind or solar, into usable DC power.In conclusion, the PBA100F-3R3-TN is an incredibly versatile AC DC converter which has wide applications in the automotive and energy harvesting industries. It operates through a voltage transfer process, whereby the incoming AC voltage is processed through an input filter, a main transformer, and a feedback transformer before being sent to an internal DC/DC converter. This converter then utilizes a Buck/Boost regulator to reprogram the input voltage to achieve the desired output. This makes the device incredibly versatile and allows it to be used for a variety of different purposes.
