Hi Denis_Volko, Welcome to EasyEDA. Please note that Voltage and Current sources in EasyEDA can be set to an initial phase value for a Transient (Time Domain) Analysis and another, separate, initial phase value for an AC (Frequency Domain) Analysis. For information and examples on how to configure Voltage and Current sources in EasyEDA, please have a look at the following sections of the Simulation eBook: https://easyeda.com/Doc/Simulation-eBook/Configuring-Voltage-and-Current-Sources.htm#ConfiguringVoltageandCurrentSources :)
