 Three phase Energy meter: It is a three phase Energy meter (1 s) designed in
compliance with IEC Standards. The meter is powered up by a flyback topology
based SMPS, comprising of powerint link switch. The measurement is done by a
high speed ADC (Analog devices make) and the microcontroller used is of TI.
The data was stored in the EEPROM through I2C protocol. It also had a
magnetic sensing circuit for Tamper detection and zero crossing detection
circuit. The meter used to communicate serially using RS232 and RS485. This
project was in compliance with IEC standards for EMI/EMC.
Oct 2011 to Feb 2014: LnT (Larsen and Toubro) as senior software Engineer
Energy Meter
 Client: LnT
 Description: Tri vector Energy meter (0.5 s) designed in compliance with IEC
Standards. The whole system was powered by an SMPS (Flyback topology).
Microcontroller used was MCF51EM256 (32 bit, freescale make). The data was
stored in the EEPROM through I2C protocol. It also had a magnetic sensing
circuit for Tamper detection and zero crossing detection circuit. The meter used
to communicate serially using RS232 and RS485. This project was in compliance
with IEC standards for EMI/EMC.
Medical Equipment safety analyzer
 Client: Fluke
 Description: An instrument used for measuring various aspects of Medical
instruments like Earth leakage, point to point resistance, chassis current etc. In
this Project, the earth leakage was current was measured voltage drop across the
resistor. The voltage signal was passed through a signal conditioning circuit
comprising of Instrumentation amp with different gains and RMS to DC
converter and finally an ADC. The ADC data was read using SPI of ARM9
Microcontroller It also used to sense high input voltage voltage using voltage

3. divider and Op amps comparator circuit. For checking point to point resistance a
current generation circuit was used. Designed as per IEC Standards.
Oct 2009 to Oct 2011: Eon Infotech Ltd. As design Engineer
DRCS

 Description: It was a circuit used in one of the missiles of DRDO. It had 48
data lines interfaced with the outside world which were stepped down from 28 v
to 3.3v using optocouplers. The whole project was developed using four layers
PCB. These signals were interfaced with ARM9 microcontroller. Serial
communication was done through RS485. Designed as per MIL Standards
VTS
 Client: In house project
 Description: It was a device used for the tracking of the vehicles and
provides the information like speed, route, Tamper etc. This information was
sent to the main server through GSM using Sagemcom-HiLo V2 and RX210
(Renesas) microcontroller.

 Description: The aim was to produce any colour of light using the concept of
colour generation through mixing of red, green and blue diffused light LEDs.
The project was implemented using DSPIC30f6010 controller and based on
PWM. This PWM was fed to an array of Red, Blue and Green LEDs through a
power Mosfet.
Robotics
 Description: A team of robots was designed to participate in a competition.
The team consisted of one automatic and other manual robot. The robots were
supposed to put blocks over towers and the team which finishes first wins the
game according to the set rules.
