Paper Abstract

Once available only as expensive custom designs, high-power hybrid PWM controllers are now available as commercial-off- the-shelf items from several suppliers at competitive prices. These units are hybrids in the sense that they provide analog front-ends, digital switching logic, and power output drivers in one package. The space and parts- count reduction provided by high-power PWM hybrids is substantial, making these parts attractive to use in large stabilized gimbal systems. Unfortunately, not all PWM hybrid designs are well suited to this application. Motor control for stabilization is discussed generally, and PWM design for stabilization application is discussed specifically. Key features of good design are identified and described in detail. Implementation issues are addressed.
