Product Description
The DC/DC converter is a power electronic device that utilizes capacitors and inductors for energy storage. Through controllable high-frequency switching technology (MOSFET, IGBT), it converts input DC voltage into different output levels, achieving boost, buck, or polarity conversion.
Using PWM modulation closed-loop feedback systems, the device stabilizes output voltage and achieves efficient filtering of electrical energy. It is widely applied in energy transmission and regulation fields.
