Our Services
Power Converters Development
Designing efficient and reliable power converters requires a deep understanding of electrical systems, circuit topologies, and component interactions. At our core, we focus on delivering tailored solutions that maximize efficiency, minimize energy loss, and meet the unique needs of your application. Whether it's for renewable energy, automotive, industrial, or consumer electronics, we specialize in designing power conversion systems that are robust, scalable, and future-ready.

Our expertise covers:
- Power topology design, calculations & part stress analysis
- Electrical simulations and component selection
- Custom magnetics and inductive components
- Analog/digital circuit design, PWM controllers
- Power switches (IGBT, MOSFET, SiC, GaN)
- Gate driver circuits and auxiliary power supplies
- PCB layout, signal and power integrity
- Control theory and algorithm development
From initial concept to final layout and testing, we ensure that every power converter we design is optimized for both performance and reliability.
Simulations
Simulations are a crucial step in modern electronics design, enabling us to test and refine concepts before committing to physical prototypes. By leveraging advanced modeling and simulation tools, we can predict how electrical systems will behave under a wide range of conditions, ensuring design accuracy and performance. Our team employs state-of-the-art simulation tools to uncover potential issues early, minimizing risk and accelerating the development process.
We use tools such as:
SPICE
SIMPLIS
PLECS
MATLAB/Simulink
Our simulation capabilities include:
- Circuit behavior analysis under steady-state and transient conditions
- Control loop tuning and optimization
- Switching, thermal, and EMI performance
- Parameter sweeps and fault simulations
Motor Control
We can deliver common but also comprehensive algorithms/controllers for different tasks.

Embedded Software / Firmware
Embedded software and firmware form the backbone of modern electronic systems. These systems must not only perform efficiently but also integrate seamlessly with the hardware they control. Whether you're working on a power converter, motor control system, or an IoT device, our team develops embedded solutions that provide real-time control, reliability, and user-friendly interfaces. We specialize in both low-level firmware and high-level applications that interact directly with hardware, ensuring that your product meets the highest performance standards.

PCB Design
PCB design is a critical part of any electronics project, as it directly affects the performance, reliability, and manufacturability of your product. At our company, we specialize in creating high-performance printed circuit boards that meet the demands of complex electrical systems. Whether you're working with high-speed digital circuits or high-power analog designs, our team ensures that the PCB layout supports optimal signal integrity, thermal management, and manufacturability. We focus on turning your schematic designs into physical, optimized, and reliable circuit boards that are ready for production.

Electronic Manufacturing Services (EMS)
Bringing your designs to life requires more than just great engineering—it requires reliable manufacturing processes that ensure your products meet quality standards and are delivered on time. In partnership with L-Tek, we offer comprehensive EMS solutions to handle everything from component sourcing to assembly and testing. Whether you're looking for small-batch prototypes or large-scale production runs, we ensure that each unit is manufactured to the highest standards, ensuring quality and performance from the first unit to the last.

Mechanical Design
For electronic products to function as intended, they must not only be electrically sound but also be physically integrated into their intended environments. Our mechanical design services—supported by our EMS partner L-Tek—ensure that your product's enclosure, thermal management, and mechanical components are carefully designed to fit with your electronics. We work with you to address mechanical challenges early in the design process, ensuring your product is easy to assemble, operates efficiently, and is ready for the real world.

Custom Inductive Parts
Inductive components like transformers, chokes, and coils are crucial for many power conversion systems. However, off-the-shelf inductive parts don't always meet the specific needs of complex designs. We specialize in creating custom inductive components that are tailored to the unique specifications of your application, whether you're dealing with high-frequency circuits, tight space constraints, or extreme environmental conditions. By optimizing inductance, resistance, parasitic elements, and other key parameters, we ensure that your inductive components perform optimally in their intended application.

PC Software
In partnership with AscaLab, we offer PC software solutions that enable users to interact with and control embedded systems. Whether you're looking for configuration software, diagnostics tools, or monitoring applications, we develop user-friendly PC-based software that communicates seamlessly with your embedded hardware. Our goal is to provide software that enhances your product's usability and functionality, while offering real-time insights and remote management capabilities.

Technical Documentation
Clear, comprehensive technical documentation is essential for ensuring the usability, safety, and maintenance of your products. Whether you need detailed user guides, application notes, or product manuals, we can help you create documentation that is both accurate and easy to understand. Our technical writing services are designed to provide clear instructions, troubleshooting tips, and best practices for your users. Proper documentation reduces support costs and enhances the overall customer experience, helping your product succeed in the market.

Design Reviews & Trainings
At every stage of your project, ensuring that your design meets all functional, safety, and performance standards is essential. Our design reviews help identify potential issues early in the process, reducing the risk of costly revisions later. Additionally, we offer hands-on training for your team, covering tools, techniques, and best practices for designing complex electronic systems. We bring years of experience to every session, helping your team grow and ensuring your project is a success.
