The debate between AC and DC power supply started at a time when development era of electronics has not dawned. So, it is quite obvious that Westinghouse and Edison debate on AC and DC in late 19th century was an uneven one and winning of AC over DC was well justified. However, the development of new electronic devices, technologies and control systems have changed the scenario significantly compared to the one that prevailed in the later part of 19th century. This presentation is an attempt to resurrect the debate with justifications for such a ‘paradigm shift’.
