[Power Supply Design Proposal Example] Cost Reduction by Combining General-Purpose Components

[Power Supply Design Proposal Example] Cost Reduction by Combining General-Purpose Components

We have responded to the requirements! We designed it by combining standard products to achieve cost optimization!

We were using a custom power supply, but we received a request to use general-purpose DC/DC converters and AC/DC switching power supplies to aim for cost reduction and shorter development lead times in the production of power supplies. In this case, by using general-purpose AC/DC power supplies and DC/DC converters, we were able to meet the required specifications. Therefore, we designed a combination of off-the-shelf components to achieve cost optimization. [Challenges] - Aim for cost reduction and shorter development lead times - Production of power supplies using general-purpose DC/DC converters and AC/DC switching power supplies *For more details, please refer to the related link page or feel free to contact us.

[Solution Case] FPGA Power Supply Design Know-How

[Solution Case] FPGA Power Supply Design Know-How

Are you struggling with the increasingly complex power design of FPGAs? Here are some solutions to help you.

The cutting-edge FPGA focuses on how efficiently it can design increasingly complex power supplies. Proper design requires the following criteria: "Selecting the appropriate power IC for the power consumption," "Controlling the power IC to meet the power-up sequence required by the device," and "Understanding the power voltage and current required by the FPGA and surrounding circuits." By collaborating between the FPGA and the board circuit design, reliable operation and optimal costs can be achieved, allowing for smooth evaluation of subsequent actual machine operation confirmation and debugging in a risk-reduced environment. 【Response Methods (Partial)】 ■ Understand power consumption in advance by selecting packages and confirming usage rates and operational specifications. ■ Consider and determine the appropriate power IC configuration based on power voltage and current consumption. ■ Design appropriate control circuits for the power voltage rise and rise sequence. *Details of the case can be viewed through the related links. For more information, please feel free to contact us.

Introduction to "Energy-Saving Power Supply Technology"

Introduction to "Energy-Saving Power Supply Technology"

Easy noise countermeasures! Achieving high efficiency and energy saving from micro loads to full load range.

This technology is compatible with PWM power supplies such as flyback and forward methods, and it uses a control method based on continuous oscillation, allowing the control frequency to be set for optimal conversion efficiency during standby (light load) and rated (full load) conditions. By aligning the frequency switch with the standby power point, further efficiency improvements during standby can be achieved. This results in high efficiency from standby to full load, enabling a reduction in power consumption. 【Features】 ■ Achieves high efficiency and energy saving from light load to full load ■ Low noise and easy noise countermeasures ■ Smaller ripple voltage compared to intermittent oscillation methods ■ Size reduction of transformers and other components due to improved efficiency ■ Usable for flyback, forward, half-bridge methods, etc. ■ Capable of driving output power up to approximately 1000W *For more details, please refer to the PDF document or feel free to contact us.

High-capacity switching power supply "Isolated System Interconnection PCS"

High-capacity switching power supply "Isolated System Interconnection PCS"

No leakage current or ground current flows from the system side due to the direct current ground.

The "Isolated Grid-Connected PCS" is a switching power supply that, due to its high-frequency isolation, does not allow leakage current or ground fault current from the grid side through the DC ground. Thanks to high-frequency isolation, commercial transformers are unnecessary, making it lighter, smaller, and more economical due to lower total costs. Additionally, it is not limited to V(S) phase grounding. Since the inverter is configured with three legs and is isolated, there are no grounding constraints, allowing for connections without restrictions on AC wiring methods. *For more details, please feel free to contact us.*
