dc.description.abstractA simple, analog, control circuit is proposed for seamless transition between source and sink modes in a Quasi-Square-Wave Zero Voltage Switching (QSW-ZVS) source/sink dc-dc converters. The inductor current is controlled by a variable-width hysteretic current mode control. The upper and lower bounds of the hysteretic band are clamped to ensure QSW-ZVS operation with a single current command and independently from the power flow direction. This enables the control of any PWM converter able to operate in QSW-ZVS with a single control loop. Implementing a complex multi-mode or look-up-table based digital control is no longer required. A 50W buck converter and a 100W boost converter are built to demonstrate the proposed control circuiten
