| description | This paper investigated the use of a high frequency LLC resonant circuit with double loop control in an electric propulsion system's secondary power source. A detailed presentation and discussion of the LLC resonant converter topology design process were given. In order to minimize switching loss when operating at high frequencies, the power switching tube's primary side used soft switching technology and its secondary side used synchronous rectification technology. This paper presented a thorough analysis of the LLC resonant converter structure, utilizing Pulse Frequency Modulation (PFM) in place of standard Pulse Width Modulation (PWM). Simultaneously, a double loop voltage-current control technique was developed that could function at constant voltage throughout the load and voltage change range. Ultimately, the simulation results demonstrate that the controller performs well and the suggested circuit converter can achieve a constant voltage across a wide range of input voltages and load steps. |
