| Popis: | The structural-algorithmic synthesis (SAS) of single-phase voltage source inverter (SPVSI) with pulse-width modulation (PWM) in this area of application is determined for the solar power system with small distortion level of output voltage. To solve this problem in this paper consider the possibility as the SAS of using the principle of multi-channel conversion (MCC) of the energy flow. At that each of the M channels uses single-phase voltage source inverter (SPVSI) with pulse-width modulation (PWM) of the output voltage. Today they are often referred to as multichannel SPVSI. When all channels are fed from a common power supply source, the outputs of the M channels are connected in parallel through transfilters, which sum up the currents of the channels and partially perform the function of voltage filtering. This concept is characterized by significantly smaller difference in neighboring quantization levels both in the output voltages of SPVSIs and the resulting output voltage of SPVSIs with MCC. Feature of multichannel conversion by PWM in these solutions is the use of voltage levels optimized for minimum total harmonic distortion (THD) of output voltage and as well as modified solutions of transfilters. This reduces the installed capacity of the equipments. The results and recommendations obtained in the basis of computer simulation are presented for their comparative assessment and design. |
