Air blower and valve control reference design for respiratory applications
Description
This reference design provides a compact system design capable of supporting motor acceleration and deceleration up to ±200 kRPM/s: which is a key requirement in many respirator applications. The design supports a number of offboard C2000 controllers including the TMS320F28027F: enabling a low-cost: sensor-less field oriented control (FOC). In addition: the design supports a wide input voltage range (6-28 V) capable of supporting both regulated line and battery power. To drive the air blower and valves: this design uses the DRV8323RS smart gate driver and DRV8847 motor driver: respectively.
