RIR POWER ELECTRONICS L

Manufactures high-power semiconductor devices, including silicon-controlled rectifier (SCR) thyristors, press-pack SCRs, Silicon Carbide (SiC) MOSFETs, MPS diodes and high-voltage capacitor discharge switches, sold to defence, railway, HVDC transmission, industrial and EV customers. End-uses referenced in management commentary include Indian Army high-power switches and rocket launcher rectifiers, Indian Railways, BHEL, data centres, AI infrastructure and HVDC links. The current operating base is a plant at Halol, Gujarat, supported by a 25kV 120kA capacitor discharge switch development, a 10 MW rocket launcher rectifier and a 10 kV/200 kA Army switch; the company is replacing ABB in Indian defence high-power switch applications. FY26 order intake was Rs 90.2 cr with a closing backlog of Rs 17.4 cr, of which 20% of orders came from overseas customers, and the first overseas order is 120 units of 5kV 125mm press-pack SCR thyristors for a US HVDC customer, to be delivered in phases through end-2026. A new Silicon Carbide (SiC) epitaxy and fabrication facility is being built in Bhubaneswar, Odisha — total project capex Rs 618 cr, of which Rs 120 cr has been spent — with epitaxy operations guided to start in Q2 FY27 once 33kV power is available. The cost shape is materials-heavy (60.2% of revenue) and capex-heavy (29.4% of revenue), reflecting the Odisha SiC build-out.
