THN 20-4812WI is a new, state-of-the-art DC/DC converter. It provides efficient bidirectional power conversion between two DC voltage sources, and is designed for applications in a wide variety of sectors, including consumer electronics, automotive, military, aerospace, medical, and telecom. This article will discuss the application field and working principle of the THN 20-4812WI.

Application Field

The THN 20-4812WI is well suited to applications requiring a high power density, low to medium power conversion, and fast transient response. It is ideal for applications in fields that need high reliability and tight size constraints, such as medical devices, defense and aerospace, automotive, and energy storage. Examples include motor controllers, battery chargers, inverters, and DC/DC converters.

The THN 20-4812WI provides regulatable output voltage and current for total control of output performance. This makes it suitable for advanced motor control applications and data center applications, as well as applications with varying loads. It also features a wide range of protections, such as input overvoltage protection, output short circuit protection, and thermal shutdown. This ensures reliable operation in all conditions.

Working Principle

The THN 20-4812WI uses full bridge dc-dc conversion technology. This topology is capable of providing both power conversion and bidirectional switching capability between isolated DC power sources. It is composed of an input bridge rectifier, an output bridge rectifier, a pulse width modulation (PWM) controller, and an active boost inductor.

The input bridge rectifier receives the input DC voltage and regulates it to the desired input voltage. The output bridge rectifier converts the input voltage to the desired output voltage. The PWM controller switches the bridge rectifiers on or off at a set switching frequency. This controls the amount of energy delivered to the output, thus regulating the output voltage. The active boost inductor further smoothes out the output voltage and reduces ripple.

The THN 20-4812WI can also be used in buck, boost, and buck/boost configurations. In buck mode, the input voltage is lower than the output voltage, while in boost mode the input voltage is higher than the output voltage. The converter can also be used in buck/boost mode, where both the input and output voltages are adjustable. This provides a wide range of voltage regulation capabilities.

The THN 20-4812WI is an efficient and reliable DC/DC converter. It is designed to provide a wide range of power conversion solutions for a variety of applications. With its wide array of protections and adjustable output voltage and current, it is an ideal solution for applications requiring high power density and fast transient response.
