High-voltage Power Supplies

FOR RADAR, ELECTRONIC WARFARE AND COMMUNICATIONS

In 1989, CPI TMD the then TMD Technologies Ltd launched the first in a range of ruggedized military power supplies that could be configured to drive virtually any manufacturer's traveling wave tube (TWT). This design was based on innovative switched-mode technology, and it remains at the heart of all of CPI TMD's amplifier and transmitter products.

The CPI TMD high-voltage power supplies offer many features desirable for modern radar and electronic warfare applications: high efficiency, ultra-low voltage ripple (low noise), high inverter frequencies, ultra-low pulse-to-pulse jitter, low throughput delay and high power density. The units are lightweight and compact with excellent thermal management, and the high-voltage sections are encapsulated with an oil-free, silicone-based compound. This provides excellent protection in harsh environments while also enabling easy maintenance.

CPI TMD offers high-voltage switched mode power supplies to drive a wide range of microwave tubes for radar, electronic warfare and communications applications. Special features include:
  • Ultra-low phase noise
  • High electrical efficiency
  • Excellent thermal management
  • Innovative design: TMD won a Queen’s Award for Innovation in 2005
  • NEW! Modular capacitor charging power supplies to special order: 20 to 100 kW (average); 6 to 65 kV
