We are accustomed to using transformers in voltage stepping applications and in providing isolation to output circuits from the loading and transient effects that affect the input. These transformers work fine in most of the scenarios we encounter in day to day life, like the mobile phone charger, DC Adapter, the Step Down transformer at the nearby electrical distribution pole etc. But, when it comes to applications where square, pulse-like waveforms are required, the conventional transformers output a distorted waveform.
Hence, for applications such as digital communications, camera flashes, radar systems and other fields where pulsed form of relatively high voltage is required, special type of transformers, ‘pulse transformers’ are required. Pulse Transformers are small in size and provide all the desirable qualities expected of the transformers designedto handle square pulses. Let us explore the structure of one such pulse transformer and try to find out how it stands apart from conventional transformers.
