Integral Cycle Control of AC Voltage Controller

Integral Cycle Control is a strategy to control the output voltage of AC voltage controller. In this strategy, load is connected to the source for an integral number of cycle of input supply and then disconnected by switching off the supply for a further number of integral cycles. This strategy is also known as on-off … Read more

Single Phase AC Voltage Controller Explained

Single Phase AC Voltage Controller is a device which converts fixed single phase alternating voltage directly to a variable alternating voltage without a change in frequency. The input and output of the device is single phase. There are two types of single phase AC Voltage Controller: Single phase Half Wave and Single phase Full Wave. … Read more

What is AC Voltage Controller? – Definition, Working and Application

Definition: AC Voltage Controller is a thyristor based device which converts fixed alternating voltage directly to variable alternating voltage without a change in frequency. AC Voltage Controller is a phase-controlled device and hence no force commutation circuitry is required.  Natural or line commutation is used. Phase control means that the phase relationship between the start … Read more

Step-down Cycloconverter Explained

Step-down cycloconverter is a device which steps down the fixed frequency power supply input into some lower frequency. It is a frequency changer. If fs & fo are the supply and output frequency, then fo < fs for this cycloconverter. The most important feature of step-down cycloconverter is that it does not require force commutation. … Read more

How to Convert Binary into Decimal?

To convert binary into decimal, each bit of the binary number is first multiplied with 2(n-1) where n is the position of the particular bit when counted from Least Significant Bit (LSB). The result so obtained are then added to get the equivalent decimal number. We will discuss the entire process / method of converting … Read more

How to Convert Decimal Number into Binary?

An easy method of converting a decimal number into binary number is by dividing the decimal number by 2 progressively, until the quotient of zero is obtained. The binary number is obtained by taking the remainder after each division in the reverse order. This method to convert decimal number into binary number is popularly known … Read more
