Selection criteria for DC-DC Buck Converters

External soft start DC-DC buck converters all have a soft-start function. After the converter starts up, the duty cycle increases gradually, allowing the output voltage to rise smoothly, which avoids inrush currents due to sudden charging of the output capacitors. Converters with internal soft start will have a constant soft start time. If the application …

What are the Types of DC-DC Converter?

DC-DC converters can be divided into two categories according to the circuit topology: basic DC-DC converters without isolation transformers and DC-DC converters with isolation transformers. The basic DC-DC converter converts the input DC voltage to the DC voltage or current that meets the requirements of the load by controlling the switch and then by capacitors, …

Introduction of Bi-directional DC-DC Converter

What is a bi-directional DC-DC converter? The bi-directional DC-DC converter is a bi-directional DC-DC converter that changes the direction of current according to specific needs while keeping the polarity of input and output voltages unchanged, realizing the bi-directional DC-DC converter in dual quadrant operation. In fact, to achieve bi-directional energy transfer, it is also possible …
