DC DC Converters

DC-DC converters are a type of power converter which are widely used for converting direct current (DC) from one source into a different DC voltage. DC-DC converters are available in a variety of shapes and sizes, with different type and voltage capabilities, making them suitable for numerous applications. This article will focus on the VQE50W-Q48-S12 DC-DC Converter,explaining its application field and working principle.The VQE50W-Q48-S12 DC-DC Converter is a basic, low-cost DC-DC converter manufactured by Vicor Corporation. It is a step up converter, meaning it is designed for converting lower input voltage to higher output voltage. It features a 50W power rating with a very low output ripple and noise (0.3mV rms max) which makes it well-suited for a wide range of industrial applications. The VQE50W-Q48-S12 also features a wide input voltage range of 3.6V to 60V and output voltage range of 12V to 48V. It has a 1:4 ratio between the input voltage and output voltage, meaning the output voltage can be four times higher than the input voltage. Additionally, this DC-DC converter also has an adjustable output voltage range of approximately 40V to 60V. This versatile DC-DC converter can be used in numerous applications.The VQE50W-Q48-S12 DC-DC Converter is commonly used in industrial, automotive, agricultural, aerospace and other applications. In industrial applications, it is often used for the generation and distribution of power in machines and equipment. Additionally, it is used in automotive applications such as the power supply for vehicle electronics. These DC-DC converters can be used for the conversion of 12V DC batteries to 24V DC in agricultural and military applications. The VQE50W-Q48-S12 is often used as a power source for active electronic facilitation components in aircraft, satellite and medical equipment, due to its high power rating and low noise operation.The VQE50W-Q48-S12 DC-DC Converter is a regulated boost converter which converts lower input voltage to higher output voltage. The basic working principle of this DC-DC converter is shown in the figure below. When the primary input voltage is applied to the transformer primary side, the magnetic flux density of the transformer is increased. This changed flux generates an induced voltage in the secondary side of the transformer. The voltage received by the rectifier is rectified and stored in the energy reservoir capacitors ‘Ce’ and ‘C1’. The output voltage is regulated by the differential amplifier which compares the feedback voltage to the reference voltage. When the output voltage is too high the amplifier will shoot down the e-transistor. This will cause the current of the transformer to decrease and hence the output voltage decreases. The converter will remain in steady state once the output voltage has reached its required value.The VQE50W-Q48-S12 step-up DC-DC converter is suitable for use in a wide variety of industrial, automotive, agricultural, aerospace and other applications. Due to its high power rating and low output ripple and noise capabilities, this DC-DC converter is ideal for achieving high power outputs with minimal energy losses. It is also known for its high performance, reliability and long service life.
