Abstract

The regular operation of bridge voltage inverter digital control system is affected by many factors. Switching frequency affects the efficient of system, single PWM pulse width and the useful space for programme. Basic frequency of MCU (Micro Control Unit) affects the operating speed of programme and the cost of system. Sampling frequency affects sampling accuracy and the time of the programme operating. By the consideration of basic frequency of MCU, switching frequency and sampling frequency, the mathematical relationship between the running time of the inverter control system programme and all factors mentioned above was established, and the reasonable range of them is determined. Both the simulation and experiments validate the results. It provides academic and practical supports for solving similar engineering problems.
