  • Step-up converter having two reciprocally clocked switches
    Patent number: 9369037
    Abstract: A step-up converter for stepping up an electrical input DC supply voltage to an electrical output DC supply voltage, including a voltage input having a positive and a negative input node, a voltage output having a positive and negative output node, a first and second output capacitor connected in series at the voltage output between the positive and negative output nodes and connected to one another via a center output node, and a first inductor connected between the positive and output nodes, a first switch, connected between the first inductor and the center output node, a second inductor connected between the negative output and negative input nodes, a second switch, connected between the center output node and the second inductor, and a total input capacitor, connected at the voltage input between the positive and negative input voltage nodes, the first and second inductors being inductively coupled to one another.
