1 Features
The ac/dc developer's kit contains a motherboard which accepts any of the plug-in controlCARDs. The
board is divided into a power factor correction (PFC) section and an isolated dc-dc conversion full bridge
(FB) section. Features of the ac/dc developer's kit include:
• Voltage and current measurements via ADC
• Over-current and over-voltage protection on the PFC side and over-current protection on the FB side
via trip zone (TZ) pins
• Closed loop digital control with feedback using 28x on-chip ePWM and ADC
• UART communications header available for host control
• A learning platform allowing the user to easily probe the most significant wave forms within a board
that is laid out conservatively and contains many test points.
• An analog and a digital header to provide easy interconnection with the EZDSP board if desired.
• Host GUI, a friendly way to control / demo the application, based on open source C# freeware
• Special hardware circuit allows experimentation with peak-current-mode control operation, if desired
• Hardware Developer's Package is available and includes schematics, bill of materials, Gerber
files,...etc
2 Hardware Overview
The PFC section accepts an ac input of 11 – 33 Vrms, while the FB section accepts a 48-V dc input.
