DC DC Converters

DC DC converters are a type of electrical device used to convert direct current (DC) from one voltage level to another. The HBS075YG-AN is a medium to high power level DC-DC converter with a wide input voltage range from 8V to 75V. It is ideal for applications such as in distributed power systems, telecommunications systems, motor control systems, and industrial automation systems. The HBS075YG-AN is a low-profile, high-efficiency, isolated full-bridge DC/DC converter designed to interface higher voltage, higher current input sources to lower voltage, lower current loads. It has an output voltage range of 0.3V to 5V and output current range of 7A/channel and operates at frequencies up to 1MHz. The HBS075YG-AN can achieve 95% efficiency, and its ECOPIC core enables ample current and voltage regulation for the most demanding dynamic and static loading applications. In addition, the device features a unique synchronous rectification designed for improved EMI performance and reduced switching losses.

Working Principle

The HBS075YG-AN series of DC-DC converters utilizes a full bridge topology with synchronous rectification and PWM control. A full bridge is a bridge circuit used for converting of DC-DC voltage. It consists of four semiconductor switches arranged in two parallel arms. Each arm contains one N-type switch (lower leg) and one P-type switch (upper leg).The input voltage is applied to two nodes of the power bridge, while the output voltage is taken from the other two nodes. The gain of the output voltage is dictated by the ratio of the input voltage to the output voltage. The input voltage of the HBS075YG-AN can range from 8V to 75 VDC input, while it can support a 0.3V to 5V output voltage range. The on/off switching of the semiconductor switches in the bridge is controlled by an external PWM signal, generated by a digitally controlled oscillator (DCO) IC. The DCO controls the switching frequency of the bridge. The DCO determines the duty cycle of the PWM signal, which in turn dictates the amount of power fed to the output load. At the end of each switching cycle, the switches are turned off and the output voltage is determined by the input voltage. An important feature of the HBS075YG-AN is its synchronous rectification circuitry. This is enabled by an on-board MosFET in the bridge, which synchronously turns on during the negative-going portion of the PWM cycle. The synchronous rectification process reduces power loss by eliminating the current leakage through the upper switches when they are in the off-state. The HBS075YG-AN also features a special over-temperature protection feature. This prevents the converter from operating at too high of a temperature, which would result in reduced efficiency and increased power dissipation. In the event of the converter reaching a certain threshold temperature, the converter shuts down in order to prevent damage.

Applications

The HBS075YG-AN is well-suited for medium to high power applications such as in distributed power systems, telecommunications systems, motor control systems, and industrial automation systems.In distributed power systems, the HBS075YG-AN can provide a highly efficient means of converting incoming power. By converting the incoming DC voltage to a voltage level suitable for downstream components, the converter can help improve system reliability. This is especially important in applications that require a constant voltage in order to maintain proper system operation. The HBS075YG-AN can also be used in motor control systems to regulate the system voltage. By regulating the DC voltage provided to motors, it is possible to control their speed and torque. This allows for much more precise control of motor performance. The HBS075YG-AN\'s high efficiency and power density also make it an ideal choice for telecom systems. By allowing for the conversion of higher voltage to lower voltages, the HBS075YG-AN helps improve overall system efficiency and reduce system costs. Finally, the HBS075YG-AN can be used in industrial automation systems for the same reasons as in telecom systems. By converting higher voltages to lower voltages, the HBS075YG-AN helps reduce total system cost and improves system efficiency. Overall, the HBS075YG-AN is a high power DC-DC converter that can be used for a wide variety of applications. It offers a wide input voltage range, high efficiency, and synchronous rectification for improved EMI performance. With its high power density and over-temperature protection feature, the HBS075YG-AN is well-suited for distributed power systems, telecom systems, motor control systems, and industrial automation systems.
