As solar adoption accelerates worldwide, inverter technology must also evolve to deliver greater efficiency, power density, and connectivity. Modern residential inverters are now required to manage energy from solar panels, battery storage, and the grid all while meeting stricter global safety standards. In this complex environment, safety capacitors play a crucial role in protecting users and ensuring reliable, interference-free operation.

Temperature stability, equivalent series resistance (ESR), and physical construction all influence how a capacitor behaves in an LC tank circuit.

In high-voltage, high-reliability applications, safety is non-negotiable. That’s why safety capacitors are essential for mitigating the risks associated with transient voltages and electrical interference. 

As energy systems evolve to support electrification, renewables, and digital infrastructure, the demands on power electronics are intensifying.  

Resonant circuits are a foundational technology in many high-performance electronic systems, enabling efficient energy control and transfer. A helpful way to visualize resonance is by comparing electrical behavior to mechanical motion. Here, we’ll break down resonant circuits using a spring-and-mass analogy and show how this applies to the fundamental LC tank circuit.  

Radio frequency (RF) generators produce alternating current (AC) at specific frequencies ranging from kilohertz to gigahertz.

Variable Frequency Drives (VFDs) are an essential part of modern motor controller design, enabling precise regulation of AC motor speed and torque. They operate by converting fixed-frequency AC power from the grid into DC, then inverting it back into AC at the desired frequency and voltage. 

Common Data Link (CDL) is a secure U.S. military communications protocol. Established by the Department of Defense (DoD) in 1991, CDL is the primary standard for intelligence, surveillance, and reconnaissance (ISR) data transmission, enabling full-duplex, jam-resistant digital communications between airborne platforms, ground stations, and naval vessels. CDL supports real-time distribution of video, imagery, and sensor data critical for modern military operations.

Knowles’ DSM supercapacitor modules use EDLC cells in series to expand energy storage capacity across a broader voltage range. Their instant charge and discharge capabilities outperform batteries, but without the shipping restrictions, thermal runaway risks, or much shorter lifespans associated with lithium-ion technology. 

Since our acquisition of Integrated Microwave Corporation (IMC) in 2020, we have extended our range of RF and microwave filtering solutions to include a wide variety of ceramic coaxial resonators, lumped element filters, and cavity filters from the VHF to the Ka band. During this time, we’ve also continued to innovate on and expand our product offering for one of our most popular filter types – the microstrip filter.
