| Abstract: | A construction of a portable PV generation system was introduced,along with which were the main circuit topology and the design of control system.Parameters of the key components were designed,and the experimental results were showed.The DC-DC converter employed a push-pull topology with high-frequency transformer,full-bridge rectification circuit and filter circuit,while a specified PWM IC was adopted in the control system.The main circuit of DC-AC inverter consisted of a full-bridge circuit and a LC filter,while an AVR SCM took the role of controlling and producing a unipolar SPWM signal,which enabled the DC-AC inverter output a standard sinusoidal voltage. |
