“…In PS-PWM, transistors are conductive for half of the period and during diode conduction, the inverter output voltage is zero. This modulation has some advantages compared to PWM but also does not eliminate the hard switching in a wide range of power control [33,36].…”

“…Bridge converters can be equipped with snubber circuits that reduce du/dt or di/dt when transistors are switching (on/off). An interesting solution is the full-bridge in which only one branch uses the LDR (coil, diode, resistor) circuit for di/dt reduction [36]. This solution may be useful if a pulse width modulation with phase shift (PS-PWM) control is used.…”

The article presents applications of systems with power electronic converters, high voltage transformers, and discharge chambers used for nonthermal, dielectric barrier discharge plasma treatment of a plastic surface and decontamination of organic loose products. In these installations, the inductance of the high voltage transformers and the capacitances of the electrode sets form resonant circuits that are excited by inverters. The article presents characteristic features of the installations and basic mathematical relationships as well as the impact of individual parameters of system components. These converters with their output installations were designed, built, and tested by the authors. Some of the converters developed by the authors are manufactured and used in the industry.

“…This design philosophy is to use PWM DC chopper to adjust the armature voltage duty cycle, and then regulate the average value of armature voltage. PWM switch is a fixed operating frequency, can adjust the ratio of the conduction time to adjust the output (supply voltage and load current) size [4].…”

DC motors are important industrial products. Directly starting a DC motor will harm the motor and the dragged equipment. This article has designed a DC motor control equipment of soft starting, stopping and many protections functions resting on the DC motor control principle and PWM technology. The advantages of this equipment are starting the DC motor continuously and smoothly, low impact torque and impact current, easily controlled, good repeatability, and small volume.
