Reservoir Load Current Boundary Three-Row Scan - Electronic Circuits XIII: Power, Rectification, and Regulation Step by Step

Load current moves ripple and therefore the minimum valley margin. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

1 A ripple row

Source peak stays 10 V, interval stays 3 s, and capacitance stays 3 F. Load current 1 A makes ripple 1 V and margin 1 V.

\Delta V=1\ \text{V},\quad m=1\ \text{V}

2 A ripple row

Source peak stays 10 V, interval stays 3 s, and capacitance stays 3 F. Load current 2 A makes ripple 2 V and margin 0 V.

\Delta V=2\ \text{V},\quad m=0\ \text{V}

3 A ripple row

Source peak stays 10 V, interval stays 3 s, and capacitance stays 3 F. Load current 3 A makes ripple 3 V and margin negative 1 V.

\Delta V=3\ \text{V},\quad m=-1\ \text{V}
