“…For approximate analysis using complex ac-circuit analysis [10][11][12][13] in this method, fundamental components of the waveforms are used for voltages and currents. This method cannot predict the various voltage and current waveforms appropriately, and the accuracy reduces as the switching frequency is away from resonance frequency (as in variable frequency-controlled converters) or as the duty ratio decreases (as in fixed frequency-controlled converters).…”

An impulse power supply has been designed, simulated, and tested in order to feed the primary of a high-frequency transformer. Pulse power system has been widely used for plasma applications. The operational principle of the pulse power system is that the energy from the input source is stored in the capacitor bank device through a dc-dc converter. Then, when a discharging signal is given, the stored energy is released to the load. The new family of ZCS converters is suitable for high-power applications using insulated gate bipolar transistors (IGBTs). The power converter can achieve zero switching with the aid of high-frequency transformer. The device is capable of charging a 0.1 μF capacitor up to 5 kV which accounts for a charging power of 5 kJ/s. The novel control algorithm is achieved which eminently considers the nonlinear control characteristics of impulse power supply. The required charging voltage, together with the constraint on the charging time, translates into a required maximum power of 10 kW reduced in this initial version to 5 kW. The difficulty to reliably control such a power at the high-voltage side practically forbids any approach featuring a more or less stabilized DC high-voltage to be generated from a conventional 50 Hz transformer through rectification.

“…However, the corona discharge treater exhibits a strong nonlinear characteristic of voltage and current. Due to this nonlinearity, a conventional voltage-source series-resonant inverter based on either dc-bus voltage control or frequency control [7], [8] has difficulty in controlling the discharge power in a wide range of 1%-100%.…”

Abstract-This paper presents control and performance of a pulse-density-modulated (PDM) series-resonant voltage-source inverter developed for corona discharge processes. The PDM inverter produces either a square-wave ac-voltage state or a zerovoltage state at its ac terminals to control the average output voltage under constant dc voltage and operating frequency. This results in a wide range of power control from 0.5% to 100%, even in the corona discharge load with a strong nonlinear characteristic. A 30-kHz 6-kW surface treatment system consisting of a voltage-source PDM inverter, a step-up transformer, and a corona discharge treater shows the establishment of a stable corona discharge in an extremely wide range of power control and, therefore, succeeds in performing both strong and weak surface treatment processes for film.

Abstract-This paper implements a wide range of power control with pulse-density-modulation (PDM) in a voltagesource series-resonant inverter which realizes a corona discharge for surface treatment of film. The use of the pulse density-modulated inverter, or the P D M inverter, enables the employment of a three-phase diode bridge rectifier as a utility interface. The PDM inverter produces either a squar+wave ac voltage state or a zero voltage state at its ac terminals to control the discharge power of a corona surface treater. Moreover, it can achieve zero-current-switching ( Z C S ) and zero-voltageswitching (ZVS) in all the operating conditions, thus leading to a significant reduction of switching losses and electromagnetic noises. A 30 kHa, 6 k W surface treatment system consisting of a voltagesource PDM inverter, a s t e p u p transformer and a corona discharge treater shows the establishment of a stable corona discharge in an extremely wide range of power control from 0.5 70 t o 100 %, and therefore succeeds in performing both strong and weak surface treatment processes for film.
