Power Electronics Design Services

Upon project completion, the customer receives a fully functional device, a prototype or software, detailed technical documentation, source codes, and PCB design files in a CAD format. The customer will receive all the necessary instructions on how to use the product. We will also answer any questions and provide training if necessary.

Yes, we carefully select materials and components, trying to find a balance between their quality and price with consideration to the project requirements. All materials we use comply with the EN, IPC, and RoHS international standards. If required, we will use components that comply with the national regulations of your country.

The cession of intellectual property rights is legislated in our contracts. We also sign a non-disclosure agreement to protect any sensitive information. We will mention your project on our website and other platforms only with your permission.

We design circuits for various types of power supplies, including:

• linear regulators
• non-isolated/isolated switch mode power supplies
• power over Ethernet (PoE)
• hot-swapping and redundant power systems

We use different semiconductor devices for different types of projects. MOSFET and IGBT are the most common solutions that are widely used in power electronics development. For some applications, we prefer SiC and GaN that provide a high level of current and switching frequency, contributing to the efficiency of the power electronic device.

We work with Li-ion, LiPo, LFP, NiCD, Ni-Cad, Ni-MH, and lead-acid batteries. Every battery chemistry has its own characteristics, so we use them in different projects for different purposes. Li-ion and LiPo batteries better suit consumer electronics and portable devices, while Ni-MH batteries are a great choice for systems operated at very low ambient temperatures.

The biggest challenges here are overheating and a high level of electromagnetic interference (EMI). Sufficient heat dissipation can be achieved with proper component placement, a large enough copper area, vias, cooling radiators, and other means. Electromagnetic interference can be restrained with EMI filters, snubber circuits, and soft switching techniques.

We provide quality control at all stages of power electronics design – at PCB design and assembly, when assembling modules, or creating firmware and applications. If necessary, we develop software for testing standalone modules and the whole product. Finished devices are tested many times. We will also carry out additional tests at the customer's request.

Testing power electronics circuits involves our standard hardware verification procedures, including ERC, DRC, electronic circuit simulators, electrical tests, etc. We also conduct load tests: the circuit is tested under actual and extreme operating conditions. Thus, the device is exposed to both regular and extreme temperatures, input voltage range, and output power.

We pay great attention to the quality of our work. The customer receives a fully functional device or software and a detailed user manual. After finishing the project, we provide a free warranty period, during which the team will eliminate any discovered defects and bugs. During the post-warranty period, we can also provide advice on possible modernization and modification of your product.

If the project requires certification, we take this into account at the earliest stages of product development. We prepare documentation for mandatory and voluntary certification in Europe, the USA (FCC, CE, UL, RoHS, and REACH), and other countries.

The timing of a project largely depends on its specifics, complexity, scale, choice of components, and logistics. For example, a project audit can take 1-2 months, while AI-based software development usually lasts much longer. We always set realistic deadlines when preparing the spec and stick to the schedule at all project stages.

Integra Sources has long-lasting and successful relationships with trusted enclosure designers. We will provide consultation and help you place an order. If necessary, we can make minor modifications on-site. During the development process, we keep in touch with the industrial design studio to ensure that the enclosure and the board match each other.

We develop projects for private enterprises and public organizations: small, medium, and large businesses, mining and manufacturing enterprises, startups, healthcare organizations, and enterprises engaged in other industries.
