When building an electronic system or application, one of the key factors that you will have to consider during the product design phase is integrating the PCB modules. Keep in mind that each module has a specific role to play in the system. Power modules are designed to perform different power-related roles.
In some systems, you may need to integrate more than one PCB power module. Maybe two or even five modules. How should implement such systems? In this article, we are going to discuss the most effective way of integrating multiple PCB power modules into a single system.
Step 1: Define and outline your system requirements
It all starts with knowing what you want to achieve with your system. You should outline all the requirements of your projects, especially the ones that are related to power.
Find out the current and voltage that will be required by different points of the systems. Obviously, your system will have input and output subsystems. You should write down their power requirements. The same applies to all other components in the system.
Knowing the requirement specifications will help to make the right choice of PCB power modules. You will also prevent possible accidents and damages that can arise due to a mismatch between the PCB power modules and the power requirements of the system.
Other than the power specifications, the system requirement definition will also highlight on all the other factors that determine the general operation of the device.
Step 2: System design
After gathering all the requirement specifications, the next step is system design. This will give you a visual outlook of the final system. Since it is an electronic system, you will create a schematic design.
This is a two-dimensional representation that shows connectivity between different components in a circuit board. The design defines the geometry of each component in a system and at the same time on the circuit board.
In our case, the schematic design will show the interconnection between multiple PCB power modules in a system. With the design, you will know the exact positioning of each PCB module in a system. The schematic design also defines the size and design specifications of the PCB power modules that will be used in the system.
Step 3: Design the power distribution network
Once you are done with the schematic design, you can proceed to create a power distribution design. Since we are dealing with the power modules, we have to pay special attention to how power is distributed in the system.
Power distribution design highlights elements such as routing and wiring of the modules in the system. It also strives to limit the possibilities of electrical noise due to the flow of electric current in the system.
While creating a power distribution design, you should also consider the current that flows through each electronic component in a system. The focus should be on both the input and the output current.
Step 4: Choose the PCB power modules
Now that everything is on paper, you can go ahead and choose the right PCB power modules for your system. Keep in mind that the system will have multiple PCB power modules. Ensure that you are fully aware of which PCB you choose and where it will be integrated into the system.
Pay attention to all the technical specifications of the PCB modules and the functions that they will do. Some modules are designed to be power regulators while others are for noise filtering. Ensure that the PCB power modules that you choose are of premium quality so that you can minimize the failure rate of your project.
Step 5:Placement of the PCBs and other components
At this point, we can assume that you have collected all the PCB power modules and other components that will make up the system. Now it is time to place and position them. Using your schematic design and as well as the power distribution design as reference points, carefully place the PCB power modules at their respective positions.
The positioning of the PCB power modules should be next to other components so as to minimize the level of wiring that will be needed. This is also done so as to reduce the voltage drop and as well as the electric noise that is associated with the movement of electric current in a circuit.
During the placement, ensure that each component remains stable at its respective position.
Step 6: Integration of the PCB power modules
After the placement, it is time to complete the process by integrating multiple PCB power modules into the system. The process entails creating functional connections between the modules and other components in the system.
The very basic level of integration entails wiring. Power modules are connected to each other and to other components using wires. In some systems, you will have to use software applications to create these connections. Tuning may be essential for more complex applications. The purpose is to ensure that the system is able to perform to the optimum level.
Step 7: Testing
The final process entails testing the integration of the multiple power modules on a single system. Start with the physical testing which will verify that everything is in its right place. You can then do functional testing to find out whether the system operates smoothly as expected.
We have discussed the steps of integrating multiple PCB power modules into a single platform. The process may be quite challenging but it is still achievable. At the end of the day, you are likely to end up with a powerful and effective application from such integration. Not only will you get a better power management platform but also you are likely to have an energy-efficiency system.
At the core of your integration process is the quality of the PCB power modules. With the right type and quality, you will be able to increase the success rate of your product. The surest way or ensure that you get quality PCB modules is by buying from reputable PCB power module suppliers and distributors. You can also get the services of electronic components sourcing agents in China who will help you purchase the right modules for system integration.
