To prevent short-circuits between the upper and lower switches of power converters from
over-current protection, the dead time is mandatory in the switching gating signal for voltage …

Benefited from the fast switching speed, Gallium nitride (GaN) high electron mobility
transistors (HEMTs) have been widely used in high switching frequency converters …

Deadtimes are required to avoid simultaneous conduction of high-side and low-side power
transistors in half-bridge power converters. During these secure times, free-wheeling current …

In comparison with silicon IGBT, silicon carbide (SiC) MOSFET is expected to reduce the
switching loss and the conduction loss and to remove external freewheeling diodes (FWDs) …

The H-bridge buck-boost converter shows better efficiency compared to all other buck-boost
converter variants due to the ability to work in buck and boost modes. The existence of dead …

This paper presents the design and operation of three-stage buck-boost converter with high
gain soft switching using closed loop proportional integral (PI) controller. The proposed …

A short period, called dead time, is implemented to prevent power switching devices from
shoot-through in voltage-source inverters (VSI). While adding dead time is required in the …

In this article, a new freewheeling circuit with a junction field-effect transistor (JFET) structure
is developed to replace the traditional high voltage diode for freewheeling in the high …

This paper proposes an adaptive dead time control (ADTC) circuit which can adjust the dead
time of switch transistor adaptively to improve the power efficiency of an inverting buck-boost …

High frequency DC-DC converters have gained more popularity due to the ever-increasing
demand on fast transient response, small solution size and high-power density in power …
