DC DC Converters

DC DC Converters are an efficient way to convert DC power from one voltage to another. This type of power supply is widely used in various applications, such as the automotive, computer, industrial and consumer electronics industries. Many DC DC converter designs use a DC/DC transformer, which is an electrically isolated power transformer that converts direct current from one voltage level to another. The most common design is the switched mode power supply, which is a voltage regulator that contains active and switching components to obtain both step-up (boost) or step-down (buck) conversion efficiency. The type of transformer used in this application is referred to as an HQA24120W480V-007-M DC/DC converter.

Application Field

The HQA24120W480V-007-M DC/DC converter is designed as a low to medium power, wide input voltage range, wide temperature operating range power supply, and is commonly used in various industrial applications, such as motor speed control, electronic ballast, transformers, variable frequency drives, and HVAC applications. In addition, it is often used in various consumer electronic devices such as televisions, projectors, electronic signs, lighting systems, and portable medical devices. These applications require higher voltage levels than those typically used in the home and therefore require a DC/DC transformer to efficiently convert the lower voltage DC power to the higher voltage DC power required by the application.

Working Principle

The HQA24120W480V-007-M DC/DC converter works by combining the features of a switching power supply and an electrically isolated power transformer. The switching power supply contains active components such as transistors, diodes, resistors, and capacitors to control the output voltage level. The input voltage is applied to the power transformer, which increases or decreases the voltage level accordingly. The transformer is then connected to the switching power supply which delivers the desired output voltage level. This combination allows for both step-up (boost) and step-down (buck) conversion efficiency for a wide range of input and output voltages.

The output voltage is regulated by adjusting the duty cycle of the switching components. The duty cycle is based on the input voltage level and the programmed output voltage level. When the output voltage is lower than the input voltage, the switching components are in a buck mode, which draws current from the input and delivers it to the output. When the output voltage is higher than the input voltage, the switching components are in a boost mode, which draws current from both the input and the output and delivers it to the output.

The HQA24120W480V-007-M DC/DC converter is a reliable and efficient DC/DC transformer for various industrial and consumer applications. It offers both step-up and step-down capabilities, allowing for a wide range of input and output voltages. Its switching power supply component helps regulate the output voltage level for greater accuracy, and the transformer ensures electrically isolated power conversion for added safety.
