Transformer Ratio Power Cross-Scan - Electronic Circuits XIII: Power, Rectification, and Regulation Step by Step

Changing secondary turns moves voltage, current, and ideal power together. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Changing secondary turns moves voltage and current together

The checked source keeps primary turns six, primary voltage twenty-four volts, and secondary current three amps. Secondary turns are three, so both side powers close at thirty-six watts.

V_s=12\ \text{V},\quad I_p=\tfrac{3}{2}\ \text{A},\quad P_{\text{in}}=P_{\text{out}}=36\ \text{W}

The ideal power ledger closes for each turns row

The scan changes secondary turns while holding primary voltage and secondary current fixed. The middle row exercises the fraction three-halves for primary current.

\begin{array}{c|c|c|c|c}N_s&V_s&I_p&P_{\text{in}}&P_{\text{out}}\\2&8\ \text{V}&1\ \text{A}&24\ \text{W}&24\ \text{W}\\3&12\ \text{V}&\tfrac{3}{2}\ \text{A}&36\ \text{W}&36\ \text{W}\\4&16\ \text{V}&2\ \text{A}&48\ \text{W}&48\ \text{W}\\\end{array}
