The voltage is a sine wave.
The current is a non-sinusoidal wave.
Find the effective value and phase angle of the current fundamental.
Find the effective value of the current (the square of the fundamental and the harmonics of the harmonics and re-open the square)
Apparent power = voltage rms value * current rms value S active power P = fundamental active power = voltage RMS * fundamental current RMS * fundamental power factor
Power factor = P / S
The rectifier circuit uses what characteristics of the diode to achieve rectification: unidirectional conductivity of the diode:When the PN junction is applied with a forward voltage, there can be a large forward diffusion current, that is, a low resistance, which is called a PN junction conduction; when the PN junction is applied with a reverse voltage, there is only a small reverse drift current, which exhibits a high resistance. , We call the PN junction cutoff. This is the unidirectional conductivity of the PN junction.
