Abstract

The invention provides a power electronic control simulation system which comprises a signal collector, a signal conditioning circuit, a digital signal processor (DSP), a power drive circuit and an upper computer. The signal collector is used for collecting measured signals and converting the measured signals into analog electric signals. The signal conditioning circuit is used for amplifying and filtering the electric signals. The digital signal processor is used for converting the analog electric signals into digital electric signals, operating and processing the digital electric signals and outputting at least a first signal. The power drive circuit is used for controlling a power conversion main circuit to be powered on or powered off according to the first signal. The upper computer is used for displaying the intermediate process control variable value in real time when the digital electric signals are operated and processed through the DSP. In this way, when a hardware system runs, the intermediate process control variable of the hardware system can be transmitted to the upper computer, and the value of the intermediate process control variable is observed in real time; meanwhile, the intermediate process control variable can be processed through an intelligent algorithm, a control result is obtained and transmitted to the DSP, and the aim of real-time control is achieved.

Description

technical field [0001] The invention belongs to the technical field of power electronics, in particular to a power electronics control simulation system. Background technique [0002] The power conversion device is an important link in the overall equipment of new energy. During the power conversion process, the conversion device has the characteristics of multiple voltages such as DC, AC, high voltage, and low voltage. At the same time, there may be overvoltage, voltage imbalance, Problems such as low voltage ride through and harmonics make it inconvenient to observe real-time signals during debugging in real time. [0003] In the field of power electronics, semiconductor switching devices are mostly used as control devices, and MCU is required to generate PWM waves to control the switching on and off of the switching tubes. When the MCU is suspended, the state of the I / O port is uncertain, resulting in the state of the PWM wave. Uncontrollable, so that the designer cannot...
