672W Highly Integrated Reference Design for Automotive Bidirectional 48V-12V Converter

TIDA-00558: Today's automotive power consumtion is 3KW, which will increase to 10KW in next 5 years and 12V batttary is unable to provide that much power. 48-12V bi-directional convertor provides high power requirement solution with two phases each capable of running 28A. This solution allows bidirectional current control of both phases using a C2000 control stick and firmware OCP & OVP. The 48-12V bi-directional converter removes the voltage conditioner need and distributes loads more evenly. The 48V battary is used to power high torque motors and other high power components such as A/C compressors and EPS, while no change to 12V battery loads.

12- to 24-V, 27-A Brushed DC Motor Reference Design

TIDA-00620: Brushed motors are a relatively popular option for motor designs because of their low price and simple control scheme. A brushed motor has a wire-wound rotor and permanent magnet stator. The commutation of the motor is achieved using conductive rings that are connected to the rotor using brushes that scrape against the commutator rings. This allows the direction of current through the motor to change based on the orientation of the brushes and different commutation rings. Utilizing an H-Bridge allows for easy direction and speed control changes to be applied quickly and efficiently to the brushed DC motor. An electronic drive is required to control the motor currents in a brushed DC motor. The electronic drive circuit consists of a power stage with two-phase inverter meeting the required power capability, a microcontroller to implement the motor speed commands and fault handling, current sensing for motor startup / stall protection, gate driver for controlling the two-phase inverter, and a power supply for microcontroller and other low voltage devices.
