How To Calculate Transistors For Making Inverters

When it comes to making an inverter, installation of transistors become an important issue. An inverter can be simply and single handedly made just by using transistors.

The oscillator stage may be built using transistors and also the output stage which may be designed using heavy duty transistors.

How to calculate transistor parameter while making inverter

A square wave inverter can be very easily built by incorporating an astable transistor stage made up of a couple of BC547 transistros and the driver stage using a couple of high power transistors like BD 135, BD 139 etc or transistors like TIP 31 etc.

The output stage can be simply made by using a couple of 2N3055 transistors or through paralleling them if greater power output is felt necessary.

However without calculating the associated resistors which define the working and the

efficiency rate of the dev ices, the whole plot may fail. Basically we need to calculate the base resistor value of each transistor, especially the output transistors. This will make sure the devices are kept sufficiently cool with optimum results from them.

Again before calculating the base resistor we well need to find the collector load of the relevant transistors. For calculating the collector load we simplt need to find the resistance of the connected load. Next through Ohm’s law we can evaluate the collector current which will eventally become the main variant in the formula for calculating the base resistor.
