=) A transformer is a device , based on the principle of mutual induction , which is used for converting large alternating current at low voltage into small current at high voltage , and vice-versa . The Transformers which convert low voltages into higher ones are called 'step-up' transformers , while those which convert high voltages into lower ones are called 'step-down' transformers . Transformers are used only in AC (not in DC) .
