Often 220V or 230V is not the highest voltage (Vpeak), but the square mean root (or secondary mean), especially the effective voltage (Vrms) as a statistical measure of the magnitude of the values that change (AC) between negative and positive. In Korea, this is called rated voltage 220V, and it is an AC sine wave that travels between +311 and -311V. Therefore, the instantaneous maximum voltage (Vpeak) is 311V.$\combi{V}_{rms}\ =\frac{325V}{2}\ =165.5V$Vrms = 325V2 = 802.5V$\combi{V}_{dc}\ =\frac{325V}{3.14}\ =\ 103.5V$Vdc = 325V3.14 = 103.5vThe 230V AC sine wave above was half-wave rectified through a half-wavelength rectifier. When + and – alternating current are repeated up and down, + passes through the rectifier and circulates through the circuit, but – does not pass. Thus, a half-wavelength current flows at R (resistance or load). The formula for calculating the voltage effective value (Vrms) and average output voltage (Vdc) of the half wavelength of such a rectified DC is as above. Average output voltage (Vdc) is the average output voltage, which means the average DC voltage after all the same as the average DC voltage.$frac{2}{frac}{pi \dev == 0.637,94 \frac+1++sqrt+2++=+0.707$2 cents=0.637,1,2 = 0.707$\combi{V}_{dc} = 0.673\times 325V = 207V$Vdc = 0.673×325V = 207V$\combi{V}_{rms} = 0.707\times 325V = 230V $Vrms = 0.707×325V = 230VThe above 230V AC sine wave was rectified as it passed through a rectifier in the radio field. When + and – alternating current are repeated up and down, the current can pass through the circuit not only when + but also when -. Therefore, the current in the radio field flows at R. In other words, the direction of the current flowing at R is constant. The formula for calculating the effective voltage value (Vrms) and average output voltage (Vdc) of such a rectified DC radio field is as above.$\combi{V}_{rms}\=\frac{1}{\sqrt{2}\cdot\combi{V}_p\ =\ 0.707\cdot\combi{V}_p\ = 230V$Vrms = 1÷2·Vp = 0.707·Vp = 230V$\combi{v}_{rms}\=\frac{1}{2}\sqrt{2}\cdot\combi{V}_{pp}\ =\ 0.353\cdot \combi{V}_{pp}\ =\ 230V$Vrms = 12vp2·Vpp = 0.353·Vpp = 230V$\combi{V}_{rms}\ =\frac{pi}{2\sqrt{2}\cdot\combi{V}_{dc}\ =\ 1.110\cdot \combi{V}_{dc}\ =\ 230V$Vrms = π2√2·Vdc = 1.110·Vdc = 230VThis is applied to pure sine files as shown above, and when the shape of sine waves and waveforms of the same half wavelength as the first is different, the formulas such as Vdc and Vrms are different.In the above case, it is the process of rectifying single-phase AC with direct current, and in the following case, it is the process of rectifying three-phase AC with direct current.$\textcolor{#000000}{\combi{V}_{peak}\ =\sqrt{2}\cdot \combi{V}_{rms}\ =\sqrt{2}\cdot 230V\ =\325V\}$Vpeak = φ2·Vrms = φ2·230V = 325V$\frac{2}{3}\pi \radian \left(30\cir \sim 150\cir \right) \Vdc of wavelength in region \combi{V}_{dc}$23πradian (30°-150°) Vdc of wavelength in region$=0.827\times\combi{V}_{peak} = \ 269V \\left(value\\value\right)$=0.827×Vpeak = 269V (標準値)oror$\textcolor{#000000}{\combi{V}_{dc}message\ peak\ =\sqrt{3}\cdot \combi{V}_{peak}\ =\sqrt{3}\cdot 325V\ =\ 563V\}$Vdc()ピーク = “3·Vpeak = “3·325V = 563v$\frac{1}{3}\pi \radian \left(60\cir \sim 120\cir \right) \Vdc of wavelength in region \combi{V}_{dc}$13πradian (60°-120°) Vdc of wavelength in region$=\ $=\ 1.655\times\combi{V}_{peak} = \ 538V \\left(value\\value\right)$ = 1.655×Vpeak = 538V (標準値)orororThe figure above shows the operation process of the diode bridge among various types of rectifiers.In the figure above, on the left side of the circuit, an AC with a change of + and – flows, but in R, a DC with a constant direction of + and – flows due to the rectifier’s rectifying action.<Picture sources and references>Diode Bridge – Wikipedia Diode Bridge According to Wikipedia, a free encyclopedia A diode bridge is an array of four (or more) diodes in a bridge circuit configuration that provides the same output polarity for both the polarity of the input.
