Abstract
Boost converters are electronic devices that are widely used to power devices that require a higher voltage than the input voltage supply can deliver. When designing boost converter systems, it is difficult to optimize component values without damaging components. Models and simulations of a boost converter are developed to give insight into how to design the system and prevent harm to the boost converter. In particular, a state-space averaged (SSA) model of a DC-DC boost converter that includes a secondary inductor and parasitic resistances is developed. This model is then further developed to match a hardware bidirectional DC-DC boost converter that operates in continuous conduction mode (CCM) and uses voltage-mode with current-mode control. The SSA model is used to simulate an actual hardware boost converter system. The SSA based simulation successfully matched experimental data of the hardware boost converter system at low (10kW) and medium (60 – 120kW) level power outputs, but only approximately matched the system behavior at high (250kW) level power outputs.
