The main idea of Active Voltage Control (AVC) is to employ classic feedback-control methods forcing the IGBT collector voltage transient to follow a predefined trajectory. This feedback control of IGBTs has great advantages in guaranteeing that IGBTs remain in Safe Operating Area (SOA), restricting EMI, mitigating the voltage/current stress, minimizing/predicting their power losses and balancing voltages of IGBTs in series. Inevitably, however, AVC introduces stability issues. Based on the assumption that accurate IGBT small-signal model parameters are available, an analogue Proportional-Derivative (PD) and multi-loop feedback control was proposed to achieve stable performance in previous work. Due to nonlinearities and uncertainties in IGBT parameters, previous stability analysis methods have important limitations. This work uses Kharitonov's theorem during the IGBT controlled turn-off to assess the system's stability and guide the AVC design to account for model uncertainties and varying parameters. We conducted experiments to investigate the system's robust stability due to these uncertainties in the IGBT parameters, which confirm the validity of the proposed theoretical analysis. With the use of wide bandwidth op-amps it is shown that the feedback design may be simplified.

“…Several researchers have proposed some voltage-equalizing circuits, such as clamp regulator [16], drain-source resistor capacitor and diode (RCD) buffer circuitry [17], synchronization pulse transformer drivers [18], and gate RCD active equalizing circuit [19], [20], to solve the uneven distribution of the static and dynamic voltages of the MOSFET series. In these equalizing techniques, the active equalizing strategy can adjust gate drive signal initiatively such that the respective MOSFET can achieve synchronized action, which protects the MOSFET from damage caused by overvoltage.…”

Several series and parallel Blumlein-type striplines designed on multilayered printed circuit board (PCB) are connected to match different impedance loads with different pulsewidths to develop a high-voltage nanosecond pulse generator for investigating the biological effects of a nanosecond pulsed electric field. First, the principle of a multistage series-parallel Blumlein stripline system is described. In particular, the multilayered strip transmission line is designed on the five-layered PCB to minimize the volume of the system whose maximum size is 300 mm (length) × 260 mm (width) × 154 mm (height), and the gate resistor capacitor and diode active equalizing circuit is used as the dynamic/static balancing tactic. Then, a singlestage Blumlein-type stripline and some multistage series-parallel Blumlein-type stripline are established to test their performance. As a result, the nanosecond pulse generator produces a rectangular pulse on a matched resistor load, with an amplitude of 0-1.7 kV, a pulsewidth of integer multiples of 100 ns, a rise time of ∼20 ns or less, and a repetition frequency of 0 to several kHz. A variety of biomedical loads can be matched by parallel stacking mode, which will facilitate the analysis of the biological effects of the nanosecond pulsed electric field.

In this paper, a multilevel current-source inverter (MCSI) topology is analyzed. The issue of constructing a novel modular single-rating inductor MCSI is explored, taking advantage of the features of field-programmable gate arrays (FPGA) for control and gate signal generation. The proposed topology is built with identical modules where all inductors carry the same amount of current, simplifying the construction and operation of industrial applications with higher efficiency. A new statemachine approach, which is easy to implement in an FPGA, and a proper implementation of the phase-shifted carrier sinusoidal pulse width modulation (PSC-SPWM) allow both current balance in all modules and effective switching-frequency minimization. The performance of the MSCI proposed is simulated with Matlab and is verified by constructing a prototype.Index Terms-Field-programmable gate array (FPGA), multilevel current-source inverter (MCSI), phase-shifted carrier SPWM (PSC-SPWM).
