. three, design examplesFigure 2, the known C1 is 0.33μf, the AC input is 220v/50hz, the circuit can supply the maximum current load. C1 in the circuit of the Tolerance XC is:xc=1/(2πf C) = 1/(2*3.14*50*0.33*10-6) = 9.65Kthe charge current (Ic) flowing through the capacitor C1 is:Ic = U/XC = 220/9.65 = 22mA. (valid value of current)The capacitance of the Buck capacitor C1 is usually approximated by the relationship of the load current IO: c=14.5 I, wh

Phase voltage or line voltage
Is the rated voltage in the power system a line voltage or a phase voltage?
Only 220 volts is the phase voltage, and others are the line voltage.
The voltage between the terminal line and the neutral line is called the phase voltage.
The voltage between two ends is called a line voltage.
In the power transmission system, there is no Neutral Line on the high voltage line, and only three-phase ABC is sent. Therefore, only
5.4. Command and response sequence
Communication between the server and the user is a dialogue process. The user sends an FTP command, waits for one or more responses from the server, and then sends a new command based on the response.
ConnectionThe response contains a lot of information. Normally, the server returns a 220 response and waits for the input. After receiving the response, the user sends a new command. If the server cannot receive the

The other two channel values (green-blue) are unchanged.For example: Pixel rgb= (127, 230, 220), where the red value is X1 = 127, the value on the corresponding curve is Y1 = 154, then the rgb= of the pixel points after the curve of the channel is adjusted (154, 230, 220)If the curve is only a 45-degree slash from the lower-left corner to the uppe
