• Refrigerator Compressor BLDC drives.


This electronics drive uses Microcontroller (IRMCF171) to control 3 phase inverter, over voltage and over current protection control. It is used to drive 3 phase BLDC motor.

Operates at mains voltage from 100Vac to 270Vac. Total power capacity of drive is 200Watt. LNK 306 based Buck converter is used for power supply section. It is used in 5 star rated Godrej refrigerators.

• DC powered BLDC drives.


This is battery operated electronics drive. It is Operated on 24V DC battery and used to drive 400W three phase BLDC motor. Microchip controller is used to control the drive functions.

It is used in DC powered Bicycles and Tricycles.

Dec2010 – Nov12 Intelux Electronics Pvt. Ltd – Pune, India. Design and Development engineer

Job Description:

Identify customer requirements, prepare product specification sheet, selection of driver IC's as well as required components, make circuit diagrams, assemble and test designed prototype for functionality, safety and EMI/EMC etc.

• Electronics Ballast for HID lamp.


This Electronics Control Gear is based on IR (International Rectifier) IC, which controls BUCK, full bridge, ignition, lamp faults, power control etc. This ECG is also an APFC controller whose THD is less than 10% and Energy efficiency index is A2. This ECG complies to all IEC standards those are required for HID driver. This ballast drives single lamp of Metal halide lamp, HPSV (High pressure sodium vapor) lamp, Mercury vapor lamp etc.

The main application is in street lights, Shop lighting, Spot lighting etc.

• LED Driver


This driver series based on fly-back topology, NCP1252 control IC is used for fly-back application. Operated on AC supply from 110V to 265V input. To improve the power factor, MC34262 is used. With this IC power factor is achieved up-to 0.99. Osram’s dragon plus and Oslon family LED’s are used for application.

• Electronics Ballast for Fluorescent Lamp.


Electronics ballast comes under IC controls and Self oscillating type. Self-oscillating model is torroid based, which is used to drive single 36W/T8 fluorescent lamp. IC based ballast is design by using Infineon made chip, which controls APFC circuit, Inverter circuit, Lamp faults etc. This ballast is used to drive 3 T5 lamps of 14W or 24W in series connection. This IC based ballast is also used to drive 4 T5 lamps of 14W or 24W in series connection. This ballast is APFC (Active power factor correction) controlled.

Key applications are Street light, Industries, Shopping malls; 36W self-oscillated used in home application.
