High Voltage Power Supplies for Radar, EW and Communications
In 1989 we launched the first in a range of ruggedised military power supplies, which could be configured to drive virtually any manufacturer's TWT. This design was based on innovative switched mode technology, and is at the heart of all TMD's amplifier and transmitter products.
Our high voltage power supplies offer many features desirable for modern radar and EW 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 but also enables easy maintenance.
High voltage switched mode power supplies to drive a wide range of microwave tubes for Radar, EW 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 Links to Queen’s Awards
- NEW! Modular capacitor charging power supplies to special order: 20-100 kW (average); 6-65 kV
