“…In order to increase efficiency, soft-switching technology has been widely used in dc-dc converters. However, most of the existing soft-switched dc-dc converters are low power [6]- [8] or unidirectional [9]- [13], and often are difficult to meet the requirements of the above applications. Full-bridge bidirectional dc-dc converters with soft switching are considered as one of the best choices for these applications.…”

Abstract-This paper presents a new zero-voltage-switching (ZVS) bidirectional dc-dc converter. Compared to the traditional full and half bridge bidirectional dc-dc converters for the similar applications, the new topology has the advantages of simple circuit topology with no total device rating (TDR) penalty, soft-switching implementation without additional devices, high efficiency and simple control. These advantages make the new converter promising for medium and high power applications especially for auxiliary power supply in fuel cell vehicles and power generation where the high power density, low cost, lightweight and high reliability power converters are required. The operating principle, theoretical analysis, and design guidelines are provided in this paper. The simulation and the experimental verifications are also presented.

“…The price to pay for this simplification in the assembly is a more complicated performance of the topology, since the use of a purely capacitive filter results in discontinuousconduction-mode operation. Nevertheless, this is not much of a problem, for the behavior of this topology has already been described and developed by means of different mathematical models for a half-bridge [20,24] where several topologies are compared, for a PRC-LCC topology [21,23,25,26]; for high voltage pulse loads [22] and full bridge Zero Current Switching Pulse Wide Modulation (ZCS PWM) application in [27]. Other models have been developed in [28][29][30][31] for LCC-type parallel resonant converter.…”

A Digitally Controlled Power Converter for an Electrostatic Precipitator

et al. 2017

Electrostatic precipitators (ESPs) are devices used in industry to eliminate polluting particles in gases. In order to supply them, an interface must be included between the three-phase main line and the required high DC voltage of tens of kilovolts. This paper describes an 80-kW power supply for such an application. Its structure is based on the series parallel resonant converter with a capacitor as output filter (PRC-LCC), which can adequately cope with the parasitic elements of the step-up transformer involved. The physical implementation of the prototype includes the use of silicon carbide-SiC-semiconductors, which provide better switching capabilities than their traditional silicon-Si-counterparts. As a result, a new control strategy results as a better alternative in which the resonant current is maintained in phase with the first harmonic of the inverter voltage. Although this operation mode imposes hard switching in one of the inverter legs, it minimizes the reactive energy that circulates through the resonant tank, the resonant current amplitude itself and the switching losses. Overall efficiency of the converter benefits from this. These ideas are supported mathematically using the steady state and dynamic models of the topology. They are confirmed with experimental measurements that include waveforms, Bode plots and thermal behavior. The experimental setup delivers 80 kW with an estimated efficiency of 98%.

“…Both are significant [1][2][3]. In general, the inclusion of these reactive elements in the circuit leads to resonant topologies [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In particular, the series parallel resonant topology, PRC-LCC, with a capacitor as output filter, fig.…”

In this paper a mathematical model for a resonant multilevel converter is presented. The topology has been conceived to be used in X-ray power supplies. The power stage has been designed to minimize the resonant current throughout the input voltage range: 400V to 750V. The inverter stage is based on the series-parallel resonant topology, LCC, to include the parasitic elements of the step-up transformer. However, the introduction of an additional magnetic coupling provides a way to modify the reactive elements depending on the output power.
