4.3.5.2. SD1L2C (Medium-Scale Diode Module Converter)

The medium-scale diode module converter changes the 3-phase current supplied from the electrical module into direct current by rectifying it through the diode module, and then store it in the electrolytic capacitor. The power generated from the motor in the robot slowing down is consumed through the transistor and resistance, and the following shows its components.
