DSP control system applied to solar power generation system

Abstract

The invention discloses a DSP control system applied to a solar power generation system. The DSP control system comprises a power supply module AC / DC, a converter DC / AC, an inverter DC / AC, a load A, a first drive circuit B, a voltage sampling circuit C, a second drive circuit D, a voltage current sampling circuit E, a control circuit F, an LCD display device G, a control algorithm adjustor TMS320F2812 and key input H. A single-phase full bridge inversion circuit is employed for the inverter DC / AC. The DSP control system is applicable to a high power occasion. The anti-interference capability of a power supply system can be effectively improved. The noise is reduced. The reliability is improved. A voltage is instantly controlled to have very high adaptive capacity to a load. The output total harmonic distortion is reduced. The loss is low.
