چکیده
Abstract A MOSFETs switching times calculation method for the known modulation strategy bidirectional buck + boost DC-DC converter is presented. former low-loss, constant-frequency based on a negative inductor offset current takes place at beginning of each conversion period which provides ability to turn converter’s MOSFET switches under zero-voltage and zero (ZVS/ZCS) condition. Time interval between half-bridge needed provide ZVS/ZCS due its antiparallel diode over an current. Described delay time estimation worst case circuit components spread allows calculate proper by Digital Control Unit (DCU). The article describes in detail input first time. clarified method, estimated voltage

متن کاملSliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency
In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
