Protocol Intro.
The latest improvements in sensors and software help autonomous robots identify and avoid workers or other obstacles to reach the destination in the shortest route, rather than just follow the established robot route.
These flexible robots, as major contributors to smart factories, need to deliver parts or finished products around the clock to accelerate delivery and reduce costs.
A robot manufacturer hopes to maximize the charging interval without affecting other performance factors.
The main objectives are: Reduce the conversion loss, and maximize the charging interval time; Reduce the size and weight to make room for larger batteries and sensors.
Scheme situation and advantages
In this scheme, the robot power supply is provided by the 48V battery pack, which can directly supply the power to the motor driver.
Power supply requires converting the battery input into three 6V and one 12V power supply to power the sensors, navigation and CPU.
The solution solution consists of four arrays of PRM and VTM converters, each providing a set of outputs.
The main advantages are: High efficiency conversion (over 92.7%) to achieve low loss; Small occupying area, thin (6.7 mm), light weight; The four PRM / VTM converters combinations provide isolation and pressure stabilization for each set of outputs.
The converter can be connected in parallel to meet the required output power requirements (6V, 60W; 12V, 600W).
Output power sorting can be easily achieved by the configured PRM.
