RIR Power Electronics Limited was formerly incorporated as 'Ruttonsha International Rectifier Limited' in 1969 in collaboration with International Rectifier Corporation, US, for the manufacture of power semiconductor devices, and thereafter was converted into a public limited company in March, 1986. Subsequently, the name of the Company was changed from Ruttonsha International Rectifier Limited to RIR Power Electronics Limited effective from 17 November, 2022. Company engaged in the manufacturing of Semiconductor devices like Diodes, Thyristors, Power Modules, Bridge Rectifiers and High Power Equipments like High Current Rectifiers, Battery Chargers, Rectifier Panels, High Power Stacks and Assembly. The Company's products are used for Industrial applications in diverse sectors such as Railways, Induction Furnace, Electricity and Power Generation, Engineering, Water Treatment, Metals, Defence, Automobiles, Oil and Gas plants, Welding Equipments, Aviation etc. The company made its maiden public offer in 1986. Initially situated at Vikhroli, Bombay, the company's unit was later on shifted to Halol, Gujarat. It came up with a rights issue in Sep.'93 to part-finance the additional working capital requirements and to finance new machinery for the indigenisation of its products. The association with International Rectifier, the US collaborator, ended in 1995, and the complete technical know-how for the silicon controlled rectifier had been handed over to the company. The c ...ompany received a technical know-how for Silicon Rectifiers and Silicon Controlled Rectifiers upto 30mm devices from M/s International Rectifier Corporation,California USA. During year 2008-09, the Scheme of Amalgamation of Orient Semiconductors Private Limited into the Company was implemented and made effective from 1 April 2007. In consideration of the said Scheme, 125 Equity Shares of Rs. 10/- each of the Company were allotted for every 100 Equity Shares held in OSPL to the eligible shareholders aggregating to 37,50,000 Equity Shares.
