Understanding the V(in)=V(max).sin(wt) Formula for DC Smoothing Circuits

Click For Summary
SUMMARY

The formula V(in) = V(max)·sin(wt) describes the relationship between input voltage and time in DC smoothing circuits. V(max) represents the maximum amplitude of the sine wave, while ω (angular frequency) is calculated as ω = 2πf, where f is the frequency of oscillation. This formula indicates that the voltage oscillates between +V(max) and -V(max), reflecting the nature of the sine function over time. Understanding this formula is essential for calculating the time at which the waveform reaches V(min) in typical power supply applications.

Can someone please explain to me in brief detail as to what each expression means for the given formula:-

V(in)=V(max).sin(wt)

and to how this formula works? It is a formula that has been given to me in order to work out time at which a waveform=V(min) for a dc smoothing circuit with a typical power supply.

A sine function oscillates between +1 and -1. Which means that the voltage you've been given oscillates between +Vmax and -Vmax. Vmax is also called the amplitude of the wave and is a measure of how "strong" this sinusoidal voltage signal is.

the sine function is a function of time, meaning that the voltage oscillates in time.

ω is the angular frequency: ω = 2πf, where f is the oscillation frequency. You can see that when t = 1/f, sin(wt) = sin(2π), and the oscillation has gone through one full cycle.
 
Thank you very much, it now makes a lot more sense to me.
