The paper presents a family of zero-current-switching switched-capacitor circuits based on the classical multiswitch switched-capacitor converters. The family of circuits consists of three topologies and provides different voltage conversion ratios. All the power devices including switches and diodes in the circuit are zero-current switching. The circuits also minimise the current stress and the pulsation current which are found in the classical circuits, The output power is higher than the classical switched-capacitor converter. Computer simulation and experiments verify the operation and performance of the circuits
