oDI0a2YxO

10*10 adjustable power supply based on TL494

Overview

The board I drew a few years ago when I first started making PCBs for free has been running for about three and a half years after successful verification. Although it is not used a lot and the ripple has not been measured, it should not be small, but he did not blow up and brought it with him. Although the temperature control fan is not very good, when I was a freshman in high school, the circuit diagram was a mess. I didn’t know how to use the network terminal
30v10a, the isolation drive transformer 15+15+15, the main transformer primary 30 turns, the secondary 5+5, must follow the high The frequency transformer specification winding
temperature control fan part can be improved. Now the fan is in a start-stop working state

A strange problem of TMS320F2812 caused by an eCAN bug
Recently, when I was adjusting F2812 to implement the CANOpen protocol, I found a strange problem. When reading the CAN message data registers MDL and MDH of F2812, the reading was 0, as shown below.
