Advancements in Solid-State Modulators

Contemporary pulsed power systems typically use solid-state modulators to maintain consistently high-voltage pulses. They operate with semiconductor switches that regulate pulses. At the same time, they reduce the need for maintenance and potential system shutdowns and downtime.

The solid-state modulator design is an upgrade from outdated thyratron-based solutions. As a result, these modulators offer superior performance and increased service life in medical equipment, radar systems, accelerators, and other applications requiring pulsed power.

At Stangenes Industries we provide a comprehensive selection of specialized transformers, pulse modulators, and electromagnetics, including the ability to customize systems and equipment for individual applications. We are ISO 9001:2015 registered and MIL-T-27- and MIL-I-45208- compliant and are committed to providing knowledgeable service, cost-effective solutions, and on-time results.

The Evolution From Legacy to Solid-State Modulators

Older modulator designs implemented thyratrons and vacuum tubes that presented multiple issues, including a large footprint, frequent maintenance needs, and an increased overall risk of failure. The change to solid-state technology improves reliability, shortens rise times, and extends longevity.

With MOSFET and IGBT switches, solid-state modulators are more compact, less costly to maintain, and less likely to fail, keeping pulsed power systems more stable.

Technical Advantages and Capabilities of Solid-State Modulators

Solid-state modulators make it easy to control the amplitude, wavelength, and frequency of electrical pulses. These highly precise and low-jitter pulses work in high duty cycles while optimizing fault tolerance and scalability through modular topologies.

Solid-state design also helps mitigate the risk of mechanical wear over time, keeping equipment fully functional for considerably longer periods than older thyratron-based models.
