Proceedings of the Institute of Electrodynamics of the National Academy of Sciences of Ukraine| Резюме: | The circuits of combined controlled rectifiers (CCR) with advanced possibilities of phase control (PhC) and pulse-width modulation control (PWM) methods of CCR switches are proposed. It is shown that the network CCR combining the Latour-Graetz rectification circuits have the widest range of the output voltage regulation (300…600 V) under the network supply ~ 220 V. The four variants of Latour-Graetz controlled rectifiers are considered. The example of generalized block-diagram of Latour (classic and double) – Graetz showed that the use of two-level PWM control is preferable. This approach makes it possible to improve the quality and effectiveness of the output voltage stabilization. The benefits of the proposed CCR (as autonomous units and as parts of power converters) are highlighted. References 7, figures 7, table. |
