In a 3-phase full converter using six SCRs, the gating circuit needs to provide one firing pulse every 60°. This is because in a 3-phase full converter, each phase operates for 180° of the input voltage waveform. To achieve full control of the output waveform, the SCRs need to be triggered at specific intervals. In a 3-phase system, there are six SCRs, with two SCRs per phase. Each SCR needs to be triggered at intervals of 60° to ensure proper conduction and control of the output voltage. Therefore, the gating circuit must provide one firing pulse every 60° to synchronize the operation of the SCRs in the converter.
