    摘要: Disclosed is a light source control device including a power conversion unit and a control unit. The power conversion unit includes a transfer capacitor provided between a primary side circuit and a secondary side circuit. The primary side circuit is configured such that a first inductor stores energy when a first switching element is ON. The secondary side circuit is configured such that the second inductor limits a changing speed of the driving current. The power conversion unit is configured such that the driving current is raised when the first switching element is ON. The control unit turns OFF when the magnitude of the driving current exceeds the first threshold value, and turns ON the first switching element when the magnitude of the driving current falls below the second threshold value smaller than the first threshold value.
