Modern power conversion circuits require intelligent power supplies that require complex control. Program switching and fine adjustment of control parameters are required depending on time/load conditions. Introducing Microchip's dsPIC® microcontroller, which is ideal for digital power control and meets these requirements.
By performing digital power control using dsPIC®, multiple functions can be integrated into one chip.
Main application examples of digital power supply
- AC-DC converter
- DC-DC converter
- PFCs
- UPS
- battery charger etc.
