About This Tool

This tool provides an accessible way to estimate the output of AC to DC converters using a simplified power-balance model. It accepts input_voltage, desired_output_voltage, and a load specification (either resistance or current) with an optional efficiency value and transformer_ratio. The core calculation derives V_out from the ratio or from the requested output and computes I_out from the chosen load model. P_out is the product of V_out and I_out, and P_in equals P_out divided by efficiency. The model supports comparison across scenarios by altering inputs and ratios, enabling rapid feasibility checks for design exploration. It is valuable for design reviews, educational demonstrations, and early-stage feasibility assessments where detailed circuit simulation is unnecessary. The tool emphasizes transparent assumptions, such as steady-state operation and a single-stage model, and highlights the impact of efficiency on input power and heat. Outputs are provided with two-decimal precision to facilitate quick decision-making and rough BOM planning. The approach is policy-agnostic and does not substitute for regulatory compliance analysis or thermal design validation.

How to Use

  1. Provide inputs: specify input_voltage, desired_output_voltage, and load specification (resistance or current) with optional transformer_ratio and efficiency.
  2. Choose method: select whether you model with a transformer ratio or use the target DC output directly.
  3. Run calculation: the tool computes V_out, I_out, P_out, P_in, and heat_estimate based on the model.
  4. Review outputs: inspect resulting voltages, currents, and estimated losses to assess feasibility.
  5. Iterate: modify inputs or scenarios to compare designs or teach concepts.

Frequently Asked Questions

Find Quick Answers

What model do you use and what are the assumptions?
The tool uses a simplified power-balance model with either a transformer_ratio or a direct voltage target. Assumes steady-state operation, a single-stage conversion, and neglects ripple, regulation, and thermal constraints for estimation purposes.
Can I use this for non-linear loads or complex power supplies?
The tool provides rough estimates for linear or near-linear loads. Non-linear or highly dynamic loads require detailed circuit simulation to capture transients, regulation, and protection behavior.
What inputs are required?
Required inputs include input_voltage, desired_output_voltage, and a load specification (load_resistance or load_current). Optional inputs include efficiency and transformer_ratio.
Is frequency relevant in the calculation?
Frequency is optional and not central to the basic DC output estimate. It may be relevant for rectification and EMI considerations in extended models, but the core calculation targets voltage and current relationships.
