Abstract:

A high amplitude, fast rising time, and high isolating strength trigger signal is needed for triggering spark gap switch. A high voltage power supply scheme was verified by means of simulation in this paper. Proper parameters of power supply circuit were selected according to the simulation result. Finally, a pulsed power supply was developed. The experimental results show that a negative pulse with 25 kV isolating strength and 15 kV amplitude can be generated by the power supply, and this generated negative pulse can meet the demand of triggering spark gap switch.

Abstract:

High Voltage (HV) switches capable of operating at high speeds and over a wide range of voltages and energies are used in a variety of pulse power applications in material science and plasma physics. Of particular interest is the use of small-scale capacitor discharges to measure the electrical properties of materials as they are heated from solid through liquid to a gas phase. In a capacitive discharge unit (CDU), energy stored in a capacitor is coupled through a switch into a low-impedance transmission line, which typically terminates with a thin sample of material.

A novel trigger generator for operating a pseudospark switch has been developed based on a modified modular multilevel converter topology using insulated gate bipolar transistors. The trigger generator can be operated in either single- or high-repetition rate shot mode. It is characterized by a fast rise time and low temporal jitter between the output trigger pulses of less than 1 ns. It produces pulses of 4.5 kV and 1 µs duration into a 50 Ω load that can trigger a single pseudospark switch. By minimizing the high-voltage components, faster high-voltage switching takes place and the power den

In this study, a device was proposed for online monitoring of high-voltage switchgears based on pulse current method and ozone (O3) detection.

This paper presents a novel soft-switching boost DC-DC converter, which uses an edge-resonant switch capacitor based on the pulse width modulation PWM technique. These converters have high gain voltage due to coupled inductors, which work as a transformer, while the boost converter works as a resonant inductor. Upon turning on, the studied soft switching circuit works at zero-current soft switching (ZCS), and upon turning off, it works at zero-voltage soft switching (ZVS) while using active semiconductor switches.

The 556 timer was picked because it is widely used, cheap and capable of producing stable dual pulse width modulations. Since, this work targeted dual DC outputs, two forward converter circuits were built. However, switching frequencies at two transistors were controlled by only one 556 timer. The com

High current applications like Microprocessors, Fuel cells, Electric Hybrid Vehicles, Solar Cells etc., use interleaved isolated buck derived converter. Interleaving of converters for such high current applications converters is done to achieve reduced input capacitor ripple voltages, output capacitor ripple current cancellation and reduced peak currents of output inductors. Generally, interleaving requires a higher number of transformers through which distributed magnetics can be achieved. i.e., one bulky transformer can be replaced with low power profile transformers.
