TRIXbox Tricks

www.controltrix.com


What do you feel when you design a power control system?


Lost on where to start ?


Going nuts over complex math and conversion?


Stressed in managing Stringent specifications …


Available digital power supply simulation software …


Expensive to buy maintain and upgrade…


Not Customizable…


Unusable broken code…


Presenting TRIXbox – One stop solution for all your design problems


e

Inclusive

• Workable and customizable end to end solution - starting from circuit parameters

• Templates for quick solution

Cost Efficient

• Beta version free

Time Saving

• Takes only a few minutes to get a complete solution without much hit and try

Flexible

• Web based application

• No upgrades, maintenance, installation, downloads, licenses

• Complete control on your data

Advantages


• Advanced techniques • Supports 360 + permutations (topologies, control modes etc)• Time and Frequency domain simulations• Simulates many second order effects• Automatic 16 bit fixed point code generation• Ideal switch simulation proprietary algorithm• Fast (compared to switched mode simulation)• Accurate (compared to averaged model simulation)

Salient Features


Technical Information about TRIXbox


•Buck•Synchronous Buck•Push Pull•Full Bridge DC-AC•Full Bridge DC-DC•Half bridge DC-AC•Phase Shift Full Bridge•Forward•Half Bridge DC-DC•Current fed push pull

Primary Topologies (more coming !!)


• Center Tap Rectifier• Current Doubler Rectifier• Center Tap Synchronous Rectifier• Voltage Doubler Half Bridge Rectifier• Full Bridge Rectifier

Secondary Topologies


• Voltage Source converter• Current Source converter

Types


• Voltage mode control• Average Current mode control• Peak Current mode control

Control Modes


• Continuous Conduction mode• Discontinuous Conduction mode

Conduction Modes


• Time domain simulation requires external inputs :• desired voltage/current• Load profile/output voltage profile• Input voltage/source profile

Time Domain Simulation


• Dead time• Finite bandwidth of feedback network• Finite bandwidth of drive• Computational delays

Second Order Effects


• Any arbitrary input profile • Automatic parabolic interpolation• Raw time value data• Discontinuities

• Predefined functions with parametric rep• sine wave• rectified sine wave• square wave• Triangle/Sawtooth wave• constant

Function Specification


• Bode plot generation• Open loop response (phase and gain margin)• Closed loop response• Disturbance rejection (Output impedance)

• Comparison of analog and digital systems• Incorporates Computational delays• Incorporates Sensor and feedback network bandwidth limitation

Frequency Domain Simulation


• Dynamic triggering• Sampling and Measurement of feedback signals depend on the

instant at which signal is sampled• User selectable/code based triggering

ADC Triggering


• Generates usable C code• Calculation of gains and proper scaling• 16 bit fixed point implementation• Starting from ADC feedback to generation of PWM signal

Automatic Code Generation


• Simulate your code with the system model in time domain• Custom algorithm• Variable PWM PERIOD, duty, Ton and Toff• Peak current Ton reset• Valley current period reset• Individual settable min,max limits for PERIOD, Ton and Toff • ADC triggering from code

User Code Mode


On request optimized solution• Buck Boost / flyback converter • LLC series resonant converter• Power Factor correction (Low Load THD specs)• Motor drives
