As energy efficiency becomes more important in modern electronics, resonant power conversion is becoming a prominent technique for minimizing energy loss in power electronics applications. The resonant inductor is an important component in resonant power conversion systems.
The importance of resonant inductors in these systems and their application in zero voltage switching (ZVS) technology, which is extensively employed in power controllers, will be discussed in this article.
What Is Zero Voltage Switching?
Power switches are turned on and off when the voltage across them is zero or close to zero using zero voltage switching. This reduces switching losses and improves efficiency, particularly in high-frequency applications. To reduce the energy losses associated with switching transients, ZVS is extensively utilized in many power conversion systems, including resonant converters.
Resonant Power Conversion
Resonant power conversion systems are designed to achieve high efficiency and minimal switching losses by utilizing the inherent oscillation of circuit parts such as inductors and capacitors. Working in intricate concert with other components, the resonant inductor plays a fundamental role within these circuits, creating an active tank that determines both system frequency and performance parameters.
Resonant Inductors in ZVS Applications
Resonant inductors are key elements in ZVS applications, as they act like a buffer that stores and releases energy based on an established pattern to generate the requisite resonance waveform for clean switching. Though not exclusive to zero voltage switched converters, their inclusion is essential for optimal performance.
By meticulously defining the inductance and quality factor of the inductor, it is possible to adjust the resonant frequency so that maximum performance can be achieved from your power converter. This optimization will guarantee a smooth transition between each switching cycle at its most beneficial point, reducing energy loss significantly.
This type of inductor is especially beneficial for applications operating at frequencies between 20KHz and 1MHz. To get the most efficient operation from a resonant inductor, it should be designed with Litz wire. This reduces copper losses and ensures that current flows evenly through all players of the wire during operation.

Our engineers can help you choose an optimized solution or provide a fully customized design to meet your specific needs. Additionally, these components utilize Litz wire which suppresses skin and proximity effects that may reduce performance when dealing with high frequency applications.
Applications of Resonant Inductors and ZVS
Resonant inductors and ZVS technology are used in a wide range of applications where energy efficiency and high-frequency operation are critical. Among these applications are:
Electric vehicle chargers
Renewable energy systems
Resonant inductors are essential components of resonant power conversion systems, allowing for great efficiency and low switching losses. The use of ZVS technology in conjunction with resonant inductors allows for even more energy loss reduction and increased performance in a variety of power electronics applications.
The ZVS resonant inductors from MPS Industries are an excellent example of a component intended to satisfy the demands of modern power conversion systems, delivering dependable and efficient solutions for a wide range of industries and applications.
Earth Day has emerged as a buzzword for the manufacturing industry.
The industry at large is becoming a proud participant in a global sustainability initiative. Local businesses sponsor community drives, and if/when capable, worldwide efforts to exhibit green commitments and spread the word.
The true essence of Earth Day is not in one-off measures or arbitrary celebrations. It is in making conservation and environmental consciousness a habit and the mainstay of everyday operations.
At MPS Industries, we build a culture around Code Green – a body of standards and practices that lets us manage our environmental responsibilities.
The History of Earth Day
Earth Day has become a massive movement with a lot of organic momentum. Every April 22nd activists and organizations in the US (and the world) dedicate time to drive home the truth about sustainability and our planet.
In recent years, there have been breakthroughs in fields like waste management and clean energy, showing the public how we can all make a difference in our environment.
Businesses in manufacturing accord it the same respect as Manufacturing Day. It is an opportunity to talk about the eco-friendly steps that the sector has taken and to cement a unique proposition for the future.
MPS Lives Earth Day, Every Day
MPS lives every day like Earth Day.
We have made eco-consciousness a non-negotiable part of our core values.
While we respect processes and the efficiency that manufacturing best practices offer, we are equally focused on the cost of our growth in regards to environmental impact.
Join us in making a conscious environmental effort by certifying for the ISO standard below.
ISO 14001 Environmental Code
At MPS, we have secured the ISO 14001 environmental code certification. We comply with stringent requirements like audits, communications, labeling, and life cycle analysis which allow us to measure the impact of our work on factors like climate change, then successfully minimize the impact.
We work with some of the most “green” sectors in the market right now including Electric & Hybrid vehicles. The shift imbues our business model – from procurement to shipping – with commitment to the well-being of the environment.
