EDS Drive Electronics
High-Voltage Traveling-Wave Drive Generator
High-voltage (1-3 kV) multi-phase traveling-wave drive generator creating the time-varying electric field that lifts and transports dust particles across the EDS electrodes.
Purpose
High-voltage (1-3 kV) multi-phase traveling-wave drive generator creating the time-varying electric field that lifts and transports dust particles across the EDS electrodes.
Context
Child of L2-DST-EDS within the Lunar Ark system
Principles
- ▸3-phase AC waveform at 10-100 Hz drives traveling wave
- ▸Voltage 1-3 kV peak-to-peak
- ▸MOSFET-based H-bridge per phase
- ▸Periodic activation (1% duty cycle) balances cleaning vs power
- ▸Rad-tolerant components for long mission
Typical implementations
- ▸NASA KSC EDS drive electronics heritage
- ▸Industrial HV piezo drivers (analog)
- ▸EDS integration on lunar landers
Lunar considerations
- ▸Long-mission HV insulator integrity
- ▸Heat dissipation modest (low duty cycle)
- ▸Coordinated with L3-DST-EDS-CTRL activation schedule
