DC/DC Controller

This controller platform was developed to drive a 60 kW DC/DC converter switching SiC MOSFET's at 40 kHz with a 1+ kV bus voltage.  The converter platform is used for energy storage applications (including wind and solar).  The design includes a Digital Signal Processor (DSP), power conditioning circuitry, voltage monitoring and self diagnostic capabilities, PWM outputs, multiple data acquisition channels, isolated CAN, RS-485 and serial interfaces. This design has proven to be a reliable solution for a variety of power electronics and control applications.


Experimental MEMS Development Kit

Serving as an extension to a team of researchers, Innovent Designs developed a platform to prove out a new type of MEMS sensor system.  The platform provided precise analog to digital conversion for the sensor outputs, clean power supply and voltage references, test points to aid in evaluating the performance of the board, and an ARM Cortex  processor.  Innovent translated the researchers algorithms from LabView into performant C code to run on the microcontroller, making use of fixed point arithmetic and FFT routines optimized for the hardware.  Innovent developed a PC desktop utility that allowed for efficient testing of the MEMS sensor, flexibly acquiring data, and adjusting a multitude of algorithmic  parameters.  The development kit was flexible enough to qualify the new MEMS technology and show that it was both accurate and suitable for low power/battery applications.

Cellular Smart Meter Module

In this project Innovent Designs was tasked with the goal of developing a communication board that could translate between a proprietary Smart Meter protocol and multiple other wireless networks.  Additionally, Innovent was tasked to develop a cellular module to pair with the communication board.  Additional wireless modules were developed by third parties.  The communication protocols supported in firmware ranged from the proprietary metering system, HTTP and  CoAP.  The system also supported a Bluetooth Low Energy interface with NFC wakeup capabilities for wireless, in-field, communication.  Furthermore, the system was designed to Class 1 Division 2 hazardous zone specifications and achieved its primary requirement to operate from a single battery pack for more than seven years.


Modbus Control Module

Designed for an Oil & Gas application, this small control board was developed to communicate over an industrial RS-485 network and process Modbus commands.  System firmware was developed for an ARM Cortex processor that needed to be both robust and allow the system to meet its low energy budget. The system was designed to meet stringent Class 1, Division 1, Zone 0 requirements for use in explosive/hazardous areas, with the production version completely potted excluding connectors.  Innovent Designs also worked closely with the Canadian Standards Association to develop safety drawings and documentation in order to bring the system through to full certification by the CSA.

Low Cost Consumer Electronics Prototype

A small, yet interesting, project was to validate a sensing methodology for use in a consumer electronics device.  In this case a development platform was needed to verify that a photodiode emitter and receiver could be used to detect an event with very high accuracy, and to develop the algorithm and firmware to process the resulting signals and perform event recognition in real time.  In order to save cost, two boards were combined into one for the sake of manufacture, but could be easily snapped apart into a sensor board and processing board, giving the developer flexibility when testing mechanical configurations of the system.  This prototype leveraged our extensive experience with data acquisition, precision analog electronics, and real time signal processing in order to create a valuable prototype and development system at a moderate cost.
