The invention discloses a three-phase T type three-level inverter sine pulse-width modulation strategy used for controlling a T type three-level grid-connected inverter and a T type three-level off-grid inverter. The three-phase T type three-level inverter sine pulse-width modulation strategy is characterized by providing a T type three-level inverter real-time SPWM algorithm, cooperation with an FPGA or a CPLD is not needed, 12 pulses needed for inverter control are generated via DSP operation, frequency of output PWM signals is greater than or equal to 20 kHz, the algorithm is completely realized in real time via calculation or function invoking, no table look-up processes are needed, and the strategy is small in calculation errors and high control precision. The strategy is simple in principle and short in realization periods and is very suitable for realizing simulation and easy DSP programming.
