Halfwave Rectifier

The basic circuit for half-wave rectification is shown in Figure (a). We can assume that the diode has essentially infinite

A rectifier that converts an AC voltage to a unidirectional voltage is used as a DC supply for many electronic

There are many types of power switching devices. Each device, however, has its advantages and disadvantages and is suitable to

Classification of the Power Semiconductors The power semiconductor switching devices can be classified on the basis of Uncontrolled turn-on and

Standard deviation is a measure of dispersion or variation amongst data. Instead of taking absolute deviation from the arithmetic mean,

There are many parameters that are important to the switches. The most important among these are : Voltage ratings: Forward

1. Empirical mode = 3 median – 2 mean When an approximate value of mode is required, the above empirical

Mode is defined as the value of the variable that occurs most frequently. Mode for Raw Data In raw data,

Arithmetic mean is the central value of the distribution in the sense that positive and negative deviations from the arithmetic

Arithmetic Mean for Raw Data The formula for calculating the arithmetic mean for raw data is: x̅ = ∑x/n x̅

Introduction Statistics is a branch of mathematics which gives us the tools to deal with large quantities of data and

There are six rules of probability using which the probability of any compound event involving arbitrary events A and B,

Consider an experiment whose sample space is S. For each event E of the sample space S, we assume that

Definitions Sample Space and Event: Consider an experiment whose outcome is not predictable with certainty. Such an experiment is called

If ∫ab f(x)dx = [F(x)]ab = F(b) – F(a) is called the definite integral of f(x) between the limits of

We study three areas where applications of integration is applied 1. Areas of curves 2. Length of curves 3. Volumes

There are two areas where derivatives are used 1. Increasing and Decreasing Functions 2. Maxima and Minima Relative maxima and

Rolle’s Theorem If a function f (x) is such that: f (x) is continuous in the closed interval a ≤

Theorem: If a function is differentiable at any point, then it is necessarily continuous at that point; proof of this
