The most common offsets are typically 90 or 120 degrees. The default firmware produces a 90-degree offset for driving single-phase AC induction motors. A three-phase ACIM may also be used with the inverter after the configuration file is modified by using the ONE_TWENTY_DEG #define inside the modulate.c file.
This inverter was originally designed to drive a single-phase AC induction motor; however, it can be used to create any arbitrary phase difference between the three outputs. This board consumes high currents and voltages with All measurements below (see Table 23 and Table 24) no isolation from the supplied input power.
Its main controller uses 32-bit arm series single chip microcomputer STM32F103. The inverter part uses three-phase half bridge. The modulation mode selects SPWM modulation technology of third harmonic injection, and uses average value feedback control at the same time.
The driving stage uses an International Rectifier three-phase gate driver for high-voltage applications. It has integrated dead time and drives six external, N type IGBTs/FETs in bootstrap operation. The inverter was designed and tested with IGBTs; however, FETs can easily be placed on the same footprint.
The inverter is strictly engineered to drive a single-phase or three-phase AC induction motor. Most of the parts in the bill of materials in Appendix A: “Bill of Materials” have been optimized to drive up to a 1⁄2 HP motor, whilst some parts, such as the IGBTs, are higher-end and give the designer more flexibility.
