Voltage Boosting Techniques in DC-DC Converters

What is Voltage Boosting Techniques in DC-DC Converters?
Voltage boosting techniques in DC-DC converters are methods to achieve high voltage gain from low input voltages using coupled-inductor, voltage multiplier, and hybrid boost topologies.
These techniques enable efficient step-up conversion for applications like photovoltaic maximum power point tracking. Forouzesh et al. (2017) review voltage-boosting methods across topologies (1965 citations). Li and He (2010) focus on nonisolated high-step-up converters for PV grid integration (1390 citations).
Why It Matters
Voltage boosting techniques interface low-voltage renewables like PV modules to grid-compatible levels with high efficiency and minimal duty cycle. Forouzesh et al. (2017) highlight applications from milliwatts to megawatts in power conversion. Li and He (2010) emphasize PV grid-connected systems addressing fossil fuel shortages. Walker and Sernia (2004) demonstrate cascaded converters improving PV array performance (903 citations). Yang et al. (2009) propose transformerless designs reducing losses in high-gain scenarios (782 citations).
Key Research Challenges
High Duty Cycle Limitations
Extreme voltage gains require duty cycles near 1, increasing switch stress and losses. Forouzesh et al. (2017) note this limits efficiency in boost converters. Middlebrook and Ćuk (1977) provide modeling for analyzing these stresses (1416 citations).
Component Stress Management
Voltage multipliers and coupled inductors face high voltage spikes on semiconductors. Axelrod et al. (2008) discuss switched-capacitor/inductor structures mitigating this (1354 citations). Yang et al. (2009) address diode reverse recovery issues in transformerless designs.
Efficiency at High Gains
Parasitic resistances degrade efficiency in high-step-up topologies for PV MPPT. Li and He (2010) review nonisolated converters struggling with this in grid applications. Franquelo et al. (2008) analyze multilevel approaches for better performance (1977 citations).
