This kit includes all parts for the control logic of a 3-phase inverter and it's interface to a power stage. That means you will need to design your own power stage. The reason is that power electronics are expensive and heavy. So first of all I don't want to stock them, second of all I don't want to ship huge parcels.

By buying a kit you will be granted technical support via email. This includes topics related to software and hardware of this kit and excludes topics related to power stage design, motor selection and other auxillary components.

If you use the material presented here without buying a kit I can not support you personally.

Images above are for demonstration only, you need to hand-populate all components (except for the red Olimex boards, of course)

Here is the complete part list:

  • 3 dual gate drivers
    • PCB
    • 2 DC/DC converters per driver
    • 2 Si8261 gate drive isolators per driver
    • all needed resistors, capacitors and pin headers
  • 2 current sensor boards
    • Board is tied directly to phase output cable
    • Melexis hall current sensors
    • all needed resistors, capacitors and pin headers
  • 1 Voltage sense board
    • Isolated bus voltage sensing
    • JCurve temperature sensor formed like a lug, so can be directly mounted on heat sink
    • all needed resistors, capacitors and pin headers
  • 1 main board
    • Olimex STM32-H103 MCU board
    • Buck converter
    • 4-channel comparator for over current protection
    • 500mA Output transistors for digital outputs
    • all needed resistors, capacitors and pin headers
  • Connectors
    • Ribbon cable
    • 24-pole pin header connector
    • 16-pole pin header connector
    • 14-pole pin header connector
    • Molex connectors (4x4-pin, 2x3-pin, 1x2-pin)
    • Olimex MOD-WIFI-ESP8266 for Wifi connectivity


If you buy this kit, you need the following parts to complete the inverter:

  • IGBTs (400A, 1200V or less depending on your requirements)
  • DC bus caps (elcap or filmcap, depending on your requirements. 800µF or more)
  • Snubber caps (about 1µF film cap)
  • Heat sink and case
  • waterproof cable bushing for power cables
  • waterproof connector for control signals
  • Mounting material for fixing the PCBs to the case (screws, angles)
