Services
Our services can be classified into following categories
1. Algorithm design and simulation
2. Implementing control algorithms in fixed point processors and dsps
3. Evaluation,feasibility study and implementation of technology, patents, research papers
4. Real time problem solving and remote support
Algorithm design and system simulation
The design of control system can be trivial and mathematically complex at the same time. At the very basic, trial and error approaches are sometimes used. Trial and error approaches are good as first approximation and help to get a feel of the system. However, meeting ever tightening specs with these methods is challenging. For better and/or optimal performance intensive mathematical analysis, simulation and expertise across multiple domains is required. We provide complete control algorithm design solution for both analog and digital motor control and power electronic systems. Simulation allows to predict the system behavior and identify pitfalls even before any hardware need to be made. The deliverables may include one or more of the following.
1. Physical system modeling and simulation to predict system behavior
2. Design of control system
3. Time domain simulation and waveforms under specified test conditions
4. Frequency domain simulation and bode plots
5. Modeling and mitigating adverse effects of second order nonlinear behavior such as inductor saturation, dead time etc.
6. Recommendations and potential pitfalls
Digital and analog implementation
For digital / DSC/ DSP based systems the control system needs to be converted into a program that will run on digital signal controller, microcontroller or dsp which has floating or fixed point capabilities. We provide conversion of the design from the conceptual and simulation stage to actual implementation on a digital platform. For analog systems we help design the feedback R-C network and the gains set by the resistors.
1. Code for pre – controller signal conditioning
2. Proper scaling of gains and parameters(conversion from the simulation level to implementation level)
3. C code for floating or fixed point machines (DSP,DSC,MCU etc) starting from ADC feedback till drive (duty or peak current reference) generation
4. Optimization of C code at algorithmic level for improving speed and memory usage
5. Handling various corner cases such as saturation and wind up
6. Recommendations and pitfalls
7. For analog sytems, we can help you design the circuit/feedback network by choosing component values
Technology review and research
Do you want to understand, evaluate and implement some technical paper, idea or patent and don’t know how to go about it? We provide expert evaluation services for the same
1. Technical Evaluation of patent, idea, research paper etc
2. Analysis and technical feasibility studies
3. Understanding technology and presenting it in black and white
4. Possible modifications, intellectual property work arounds, add ons etc to make technology more usable and valuable
5. Researching technologies
6. Pros and cons of certain methods and implementation
Need based support services

Salient features of trixbox
Overview
Trixbox is a software tool that allows users to do their end to end control system design for digital power conversion for power electronics applications. Control system can be trivial and extremely complex at the same time. It can be trivial when trial and error methods are used. It can be extremely complex when proper analysis and systematic approach is required. Trial and error is quick and dirty but may not always meet the specs and handle various corner cases. A systematic approach is complex and mathematically involved and requires considerable skill and expertise. Trixbox uses systematic analytical methods to get your design started quickly.
Salient Features
-- Automatic generation of control coefficients
-- C Code implementation of digital control system for fixed point DSC/DSP. Directly use the code with control coefficients in your application
-- 9 topologies derived from buck converter, current and voltage source converters. (more being added)
-- Discontinuous and continuous conduction mode operation
-- Voltage mode, Current mode and Peak Current mode operation
-- Simulate and plot time and frequency domain results
-- Digital system quirks like Zero order hold, quantization, computation delays handled during simulation
-- Dynamic triggering (user programmable)
-- Fast simulation of most key parameters. Better and more accurate than averaged models. Faster than most popular simulation tools.
-- Easy to use web app. Download file, modify parameters and upload. No installations, upgrades and maintenance.
-- Write your own custom code and perform the system simulation. Supports modes like variable period, duty ,on time, off time, valley current period reset, dynamic triggering of ADC for measurement.
