Remote Power Stage

The Remote Power Stage (RPS) offers two channels of motor drive control while pulse width modulating up to 280V of bus voltage. The RPS allows for feedback and control circuit pass through via a 28V common bus. The box is sized to maximize application of core IGBT module in a sealed enclosure.

Overview

RPS architecture is a scalable system design for thrust vector control. It utilizes a common CEU with a stage specific output power module. The two module design allows the power electronics to scale as the power needs change over each stage of launch vehicle. The CEU remains the same across the stages and allows commonality of interfaces and data bus communication.

Key Features:

Isolates high voltage components from low voltage controls
Battery initiation capability
Additional HV Input connector for ground support and pre-flight check-out
2 Channels of 3-phase motor bridge
2 Channels of 3-phase motor current sense
Built-in Monitors and Fault Detection
Supports modular architecture solutions
