A Booster and PWM Based Power Amplifier for Reaction Wheel
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Reaction wheel is an inertial actuator in a spacecraft attitude control system and is used to generate suitable attitude control torques for correcting spacecraft attitude deviation or adjusting to an assigned attitude. As back emf increases with speed, we have to provide high voltage as input to the motor. The boost converter is the best choice to boost up the voltage received from the solar panel to a required level. Also a PWM based power amplifier is essential to energize the coils of the reaction wheel. This paper gives the design of a boost converter with variable input voltage in the range from 28V to 40V and which is capable of boosting up the voltage to 50V with 2A as output current. This output voltage will be the input to PWM based power amplifier.
