Abstract
In this article, a high-voltage-gain boost converter (HVGBC) is designed, analyzed, and implemented. The designed HVGBC topology incorporates a single-switch boost converter with multilayer capacitor–inductor–diode–capacitor (<italic>CLDC</italic>) stacked circuits for conversion of low-voltage input into high-voltage output. To reduce the core dimensions and inductor value, HVGBC inductors are designed to operate in discontinuous conduction mode, and peak-current-mode control is used. This study is the first to consider the number of <italic>CLDC</italic> circuit layers, inductance, and duty cycle of an HVGBC; moreover, element parameter derivations and calculations are provided for determining the withstanding voltages and currents of these elements. Complete design procedures are described in detail for the construction of a low-power HVGBC prototype that is lower than 20 W; this prototype used a commercial pulsewidth modulator to achieve voltage and peak-current-mode control. In the HVGBC, three- and four-layer <italic>CLDC</italic> stacked circuits were employed to achieve a high step-up ratio.
