High-voltage DC power supplies are used in several applications, including X-ray, plasma, electrostatic precipitator, and capacitor charging. However, such a high-voltage power supply has problems, such as a decrease in reliability, owing to an increase in output ripple voltage, and a decrease in power density, owing to an increase in volume. Therefore, this study proposes a method for improving the power density of a parallel resonant converter using the parasitic capacitor of the secondary side of the transformer. Due to the fact that high-voltage power supplies have many turns on the secondary side, a significant number of parasitic capacitors are generated. In addition, in the case of a parallel resonant converter, because the transformer and the primary resonant capacitor are connected in parallel, the parasitic capacitor component generated on the secondary side of the transformer can be equalized and used. A parallel cap-less resonant converter structure developed using the parasitic components of such transformers is proposed. Primary side and secondary side equivalent model analyses are conducted in order to derive new equations and gain waveforms. Finally, the validity of the proposed structure is verified experimentally.

A phase-locked loop (PLL) control system based on field programmable gates array (FPGA) is proposed through analyzing the model of three-phase unipolar-driven BLDCM (brushless direct current motor) to enhance the reliability and accurate steady-state speed for magnetically suspended control moment gyroscope (MSCMG). The numerical operation module, PLL module and current-loop control module are designed based on FPGA using very-high-speed integrated circuit hardware description language (VHDL) to realize the control law of the digital system. The pulse width modulation (PWM) generating module for Buck converter, the commutation signal generating module for the inverter and ADC module are designed for driving the motor and sampling the current signal. The PLL is analyzed and optimized in the paper and all the modules are verified using the software of ModelSim and the experiments. The simulation and experiment results on BLDCM of MSCMG show that the stability of the motor velocity can reach 0.01% and 0.02% respectively by the PLL technology based on FPGA, which is difficult to be obtained by conventional proportion integral different (PID) speed control.

Abstract The ion or plasma nitriding process has been around for many decades. Developed in the late 1930s, the process was used extensively in Europe. During the 1980s, the process became more popular in the U.S., and many systems were purchased. Early on, the process was not widely understood, and some applications were not a good fit. As plasma nitriding advantages and limitations became realized, the process found its niche in many different industries. Very demanding applications proved to be good applications for ion over gas nitriding. In general, plasma nitriding uses high voltage power operating in the 500–100VDC range, often conducting hundreds of amps to power the process by activating the glow discharge. The glow discharge is not only capable of heating the parts but also ionizes the atmosphere to allow the process to operate. This paper provides insight into plasma nitriding and discusses new advances, widening the range of applications for the process. Many of the advances are in the form of advanced process control electronics, mass flow controllers for process gas flow, and, most importantly, newer high voltage power supply designs with high speed microprocessor arc detection technology.
