The full-bridge series-parallel resonant converters (also known as LCC resonant converters) with capacitive output filter is evaluated in high output voltage (>50 kV), high power (>50 kW) and high frequency (20 kHz) ESP (Electrostatic Precipitator) power supply applications. By using the leakage inductance and the winding capacitance of the transformer as the resonant elements only an additional...
The paper presents an innovative off-line low profile converter design that delivers 750 W of power at 95%-96% efficiency for nominal input range, using variable frequency topology with high frequency zero voltage switching (ZVS) and zero current switching (ZCS) for primary switchers. Theoretical considerations and practical results are presented for high frequency and high voltage soft-switching...
This paper proposes a new integrated magnetics (IM) ZVS full-bridge Dc-Dc converter, which integrates three inductors and one transformer with a single core. Compared with the discrete solution, the proposed integrated converter has less components, smaller size, lower cost and reduced core losses. The leakage inductance of the transformer is used as energy storage inductance and the output filter...
