Research Interests:
Parthipan is in his second year of EngD programme and is based at his sponsor company TWI. His current research interests include many areas of Instrumentation and most of his current work is in the area of system modelling. He specialises in the design, development and optimisation of battery powered power electronic circuits (Switch mode power supplies) and piezoelectric sensor drive circuits.
EngD Research:
Long Range Ultrasonic Testing (LRUT) technique is a subset of Ultrasonic Non Destructive Testing (NDT) method. This technique has the ability to detect defects for many meters in different shapes and type of structures such as pipes and plates. The technique ensures that the material and its mechanical properties are not damaged.
Battery operated electronic equipment called Teletest facilitate LRUT technique. The structural integrity monitoring of large structures such as Floating Production Storage and Off-loading Vessels (FPSOs) and sub sea installations require Teletest based distributed sensor network (DSN) as shown in figure 1. The intended DSN is composed of multiple numbers of Teletest modules deployed very closer to the phenomenon. It makes the DSN to work unattended for longer duration. Providing adequate power source to DSN is critical for the success of the operation.
Computer system modelling forms a virtual test platform where power requirement of such systems can be estimated by simulating the system model for various functionalities and scenarios.
Figure 2 depicts the subcomponents of the DSN system model. It is a complex multi discipline design.
It covers a wide range of frequencies, dimensions, environmental constraints such as temperature and humidity and power. It also crosses various different engineering disciplines such as circuit design, electromagnetic designs, mechanical and material engineering design, thermal design and reliability/life cycle engineering.
The research addresses systematic process for developing and analysing this system model. SPICE based EDA tools are used for modelling and simulations.
