High voltage pulse transformer driver

 · Most of the modern high-current high-voltage pulsed power generators require several stages of pulse conditioning (pulse forming) to convert the multimicrosecond pulses of the Marx generator output to the ns pulses required by a number of applications including X-ray radiography, pulsed high-current linear accelerators, Z-pinch, isentropic compression, and . High-voltage integrated-circuit (HVIC) based gate drivers are popular due to their simplicity in driving a half bridge stage, and have been used in power supplies and motor drives for a long time. International Rectifier (IR) was the leading manufacturer of HVIC gate drivers based on junction isolation. Ultra High Power Voltage Air Core Pulse Transformer. Basic Specifications: Energy is 5 Kilo Joules (a real treat to see the discharge in action!!) Primary is a copper sheet mm thick; Input pulse: 10Kv to 18Kv max at 50 to 60KA; Output pulse: Kv at high peak current!! Isolation: Kv pulse; Temp: 20 to 55 C.

Pulse transformers have been widely used to provide galvanic isolation between controller and power switches by isolating the command signals from the LS gate driver. However, besides being a bulky solution, it has other. The example is a pulse transformer that drives the gate of a voltage-controlled power MOSFET. The transistor selected is the industry-standard 2N, a V, 8A, ohm, n-channel device. The input of the MOSFET looks like a capacitance connected from the gate to the source of the device. driver with pulse transformer driving capability. It has been optimized for both capacitive load drive and pulse transformer demagnetization. Figure 2: Circuit block diagram It can therefore directly drive a low side switch and, through a pulse transformer, an high side switch. Its low buffer RDS(ON) can conduct a demagnetizing current of mA.

Trigger Pulse should rise and fall fast enough to decrease switching loss. 2. To reduce the Drain-to-Source drop voltage Vds when on state, sufficiently high. voltage multiplier. The zero-voltage switching circuit drives the primary of the transformer in parallel with a capacitor. With this driver, the tank. from a pulse-generating circuit driving a high-voltage pulse. transformer, which increases the output pulse voltage to the. value needed at the load.
