AC/DC converters are devices used to convert alternating current (AC) input into a direct current (DC) output. These types of converters are used in many industries and applications, including but not limited to, telecommunications, medical equipment, automotive, and power supplies. U7Y0098 is a type of AC/DC converter commonly used in all of these industries. This article will discuss the application field and working principle of the U7Y0098.

The U7Y0098 AC/DC converter is a single-phase pulse width modulation (PWM) type AC/DC converter. It is a transformerless design which offers high efficiency, small size, and low cost. It is a high frequency type of converter, typically operating at around 100KHz. It is designed to provide a well regulated DC output despite changes in AC input voltage and load current.Its maximum continuous ratings are 400V input supply, 1kW output power, and 32A peak current.

In terms of its application field, the U7Y0098 is used in many applications where a steady direct current output is required, such as computers, motor controls, and medical devices. It has been used in commercial applications such as lighting systems, HVAC, industrial automation, and renewable energy. In terms of consumer applications, it has been used for battery chargers, portable electronics, communication devices, and home appliances.

The working principle of the U7Y0098 is based on pulse width modulation (PWM). In a PWM voltage mode controlled AC/DC converter, the input AC is rectified and then converted into a DC voltage. This voltage is then used to create a voltage reference signal (Vref) which is compared to the output voltage of the converter. If the output voltage is lower than the reference signal, the PWM signal output will turn the switch on, allowing the current to flow, effectively raising the output voltage. Conversely, if the output voltage is higher than the reference signal, the PWM signal will turn the switch off, effectively lowering the output voltage.

The U7Y0098 is equipped with a wide range of protection features such as overload protection, overvoltage protection, and short circuit protection, which prevent damage to the converter and the connected system in the event of an abnormal situation. It is also equipped with an active current limited control, which limits peak current and energy to reduce the risk of over current fault and minimize audible noise. Additionally, the U7Y0098 is equipped with an integrated temperature sensing feature to ensure the system is operating safely and within the defined temperature range.

In conclusion, the U7Y0098 is a high frequency PWM type AC/DC converter designed to provide a steady direct current output with good voltage regulation. It is widely used in many industrial and consumer applications, and is equipped with various protection features to ensure the system is operating safely and efficiently.
