Interleaved DC-DC Converter

Our product PVIDCBC25 DC-DC interleaved boost converter is a type of power converter that steps up a lower input voltage to a higher output voltage level using multiple inductors and switches that operate in parallel with each other. The converter divides the input and output voltage into multiple phases, each comprising a pair of inductors, switches, and diodes, to distribute the input and output current evenly among the inductors, reducing the current ripple and enabling the converter to handle higher power levels than traditional boost converters. During operation, the switches are turned on and off alternately at a high frequency, causing the inductors to charge and discharge. The inductors act as energy storage devices, storing energy during the on time of the switch and releasing it during the off time to maintain the output voltage. The interleaving of the inductors reduces the input and output ripple, resulting in a smoother output voltage. The DC-DC interleaved boost converter offers several advantages over traditional boost converters, including increased power handling, improved efficiency, reduced EMI noise, better current sharing, lower ripple, faster transient response, and scalability. It is widely used in various applications, such as LED lighting, battery charging, and power supplies for industrial and automotive systems.
