Security and inspecting robots
Robots can go where people cannot, keeping them out of harm’s way while maintaining safety and security. Inspection robots can monitor infrastructure more frequently and allow for rapid remediation before problems occur, saving lives, time, and money. These robots need to be compact and rugged to access confined spaces, and they need to support a host of sensors and actuators to monitor efficiently and effectively. Some, with tethers, operate at high voltages of 400V with conversion down to 12V and 1.5kW for propulsion.
The power delivery network
In this example, one DCM4623 isolated, regulated DC-DC converter module converts the 300V tether voltage to 12V to power the controller while another provides a 48V bus that is further converted down to 18V using DCM3623 modules to power a set of thrusters to propel the robot. This modular PDN is smaller than a couple of mobile phones but supplies 1.5kW at 92% efficiency.
Input: 9 – 420V
Output: 3.3, 5, 12, 13.8, 15, 24, 28, 36, 48V
Power: Up to 1300W
Efficiency: Up to 96%
As small as 24.8 x 22.8 x 7.2mm
