A circuit for generating reference voltages for an A D converter is presented. The circuit consisting of a bandgap reference and a driver circuit is capable of operating on sub 1-volt supply voltages. The circuit is designed using a standard 0.5 p m CMOS technology. Simulations show maximum 0.24% variation in the generated reference voltage over a temperature range from -20 "C to I00"C and a su...

SLAC National Accelerator Laboratory is developing a next generation H-bridge switch plate [1], a critical component of the SNS High Voltage Converter Modulator [2]. As part of that effort, a new IGBT gate driver has been developed. The drivers are an integral part of the switch plate, which are essential to ensuring fault-tolerant, high-performance operation of the modulator. The redesigned dr...

The model of the new zero-voltage and zero current switching energy recovery display driver for a Plasma Display Panel is proposed. This operation helps to achieve the zero-voltage turn on of all main power switches and zero-current turn-off of all auxiliary power switches, reduce the EMI noise, current stress in Mode 2 and Mode 3 operation, and improve the energy recovery capability. This pape...

Piezoelectric transducers are known to exhibit less hysterisis when driven with current or charge rather than voltage. Despite this advantage, such methods have found little practical application due to the poor low frequency response of present current and charge driver designs. This paper introduces the compliance feedback current driver containing a secondary voltage feedback loop to prevent...

This report provides a summary of the design and testing of an active balancing circuit for three-phase AC motor drivers. The circuit actively compensates for the imbalances in the driver circuitry by driving the 0-volt ground on the circuit board relative to the common chassis of the load and the circuit board. The active balancing circuitry was able to reduce the common-mode current on the ph...

This paper proposes a gate driver integrated circuit to prevent breakdown of switching power amplifiers. The proposed circuit consists of a dead-time generator, level shifters, and a breakdown blocker. The dead-time generator makes non-overlapped input signals and the breakdown blocker detects instantaneous turned-on input signals and resets them to the off-state before the switching power cell...
