Understand the estimate and its limits.

Defined educational models

The main workbench supports sinusoidal single-phase constant-drop rectification, idealized capacitor discharge with current or resistance loads, and a downstream regulator-stage estimate. Separate full-wave and half-wave reference tools use ideal zero-drop diodes. Three-phase, SCR firing control, inverter behavior and complete offline SMPS control are outside these calculators.

Conditional regulation, not a product specification

A requested regulator output is shown only after the supplied minimum input and headroom pass the model's check. Current capability, thermal suitability, stability, protection and datasheet limits still require assessment. Switching efficiency is supplied by the user; it is not predicted. Stage efficiency is not complete AC-to-DC efficiency.

Omitted physical behavior

Rectifier/filter estimates omit source impedance, finite charging intervals, dynamic diode characteristics, capacitor ESR and tolerance, leakage, inrush, transient loads and thermal effects. A 20% crest-ripple guardrail limits the simplified filter model's scope; it is not a certified accuracy bound or equipment rating.

Electrical safety

Calculations and educational diagrams do not replace isolation, component ratings, protective design, appropriate measurements or qualified engineering review. Mains voltage and stored capacitor energy can cause severe injury. Diode rectification does not provide isolation. The diagrams are explanatory models, not complete wiring or construction instructions.
