When the transformer is on load, the secondary winding is connected with load as in figure (1) and current I2 is flowing through load. Operation of Transformer On load Figure (1) shows a transformer with a load connected across the secondary winding. The load current I2 flowing through the secondary turns sets up its own

A Push Pull Converter is dc to dc converter that provides an output voltage that can be either less than or greater than the dc input voltage VS. The push-pull converter give multiple outputs with single input. This can be achieved by changing the winding’s turns ratio of the transformer. Push-pull designs are popularly used in

A Pirani Gauge is a type of thermal conductivity gauge used to measure low vacuum pressures. It operates based on the principle that the thermal conductivity of gases changes with pressure. This gauge is widely used in vacuum technology due to its simplicity and reliability in measuring pressures from 0.5 Torr to 10-4 Torr.
