Experiment #5 – Gate Driver High-Side and Low-Side Switches
ثبت نشده
چکیده
A low-side switch is a MOSFET or an IGBT that is connected to the ground-referenced and is not floating. In a boost converter, the source terminal of the MOSFET is connected to the circuit ground, which is referred to a low-side MOSFET. To switch an N-channel MOSFET of a boost converter on, the V should be in the order of 10 to 20V. Since the source terminal is grounded, this implies that the gate voltage must be 10 to 20V. This voltage level can be easily generated by having the input voltage of the boost converter and does not pose any challenge for gate driver circuit.

Simulation Analysis of an Effective Gate Drive Scheme for a New Soft-Switched Synchronous Buck Converter
This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simu...

This work is about the analysis of dead time variation on switching losses in a Zero Voltage Switching (ZVS) synchronous buck converter (SBC) circuit. In high frequency converter circuits, switching losses are commonly linked with high and low side switches of SBC circuit. They are activated externally by the gate driver circuit. The duty ratio, dead time and resonant inductor are the parameter...

متن کاملA High-Temperature, High-Voltage Linear Regulator in 0.8-μm BCD-on-SOI
The sale of hybrid electric vehicles (HEVs) has increased 10 fold from the year 2001 to 2008 [1]. Thus, high temperature electronics for HEV applications are desired in the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. Power converters (i.e. DC-DC converter, DC-AC inverter) inside the HEVs require Gate-Driver ICs to control the power switches....
