DC DC Converters

DC DC converters are devices that convert a direct current (DC) input voltage to a regulated direct current output. DC DC converters are used in a wide range of applications as they facilitate direct current power conversion from one voltage level to another. One such device is theTHD 12-2421WI DC/DC converter. This article provides a detailed analysis of its application fields and working principle.

Application Field of THD 12-2421WI

The THD 12-2421WI is a six-wave rectified full-brick DC/DC converter designed for high output power applications. It is suitable for POL (Point of Load) applications, such as servers, workstations, power supplies, grid-tied storage, and home/industrial automation. Its strong integration capability and high power conversion efficiency enables it to be used in various applications with no external components. Additional features of the device include high isolation voltage, wide input voltage range, integrated EMI filter, and over-current protection.

Working Principle of THD 12-2421WI

The THD 12-2421WI follows a buck topology, which relies on the creation of a low resistance path to reduce the output voltage. It uses a synchronous rectifier to output a constant voltage with high efficiency over a wide range of input voltages. The input voltage is applied to the primary winding of the transformer, which steps the voltage up or down depending on the turn ratio. The switching devices in the converter, typically MOSFETs, then regulate the output voltage by controlling the primary current of the transformer.The device includes a control circuit that prevents over-current and over-voltage, and a soft-start circuit that eliminates inrush current while providing surge protection. Additionally, it has built-in temperature sensing circuitry to provide over-temperature protection.The output voltage of the device is also adjustable, which can be done by applying a voltage to the ON/OFF pin. When a certain voltage is applied, the IC begins to generate an error signal, which reduces the duty cycle, thereby maintaining a stable output voltage.The THD 12-2421WI has one of the highest power conversion efficiency on the market, reaching up to 93%. It can also be used in parallel configuration, allowing for a higher output power.
