“…However, the inductor leakage issue relates to the voltage spike on the power switch. Therefore, this study used a coupled inductor step-up circuit with a clamp circuit, which absorbed energy from the leakage inductor of the coupled inductor and supply the energy back to the output terminal of the capacitor during the next period [24,25]. Using a clamp circuit prevents spikes on the switch, and the main switch voltage stress is clamped at a voltage of 1/7 V o .…”

Abstract:In this study, a novel high step-up DC-DC converter was successfully integrated using coupled inductor and switched capacitor techniques. High step-up DC-DC gain was achieved using a coupled inductor when capacitors charged and discharged energy, respectively. In addition, energy was recovered from the leakage inductance of the coupled inductor by using a passive clamp circuit. Therefore, the voltage stress of the main power switch was almost reduced to 1/7 V o (output voltage). Moreover, the coupled inductor alleviated the reverse-recovery problem of the diode. The proposed circuit efficiency can be further improved and high voltage gain can be achieved. The operation principle and steady-state analysis of the proposed converter were discussed. Finally, a hardware prototype circuit with input voltage of 24 V, output voltage of up to 400 V, and maximum power of 150 W was constructed in a laboratory; the maximum efficiency was almost 96.2%.

“…Because there is several milliseconds delay (for easier description, set = = , where means the delay when the switch turns on, while means the delay when the switch turns off) between command send from MPU and execute by mechanical device, so the command sending time must be ahead the next AC zero point whichcan ensure the switch acts accurately at the power zero crossing point [5][6]. Command sending point…”

This paper proposed a high voltage conversion ratio cascade boost converter topology composed two stages of converters. First stage boosts the input source voltage twice larger by using the double-mode switched-capacitor cells converter (SCC). Second stage provides a high voltage conversion ratio boost converter with a couple inductor and diode-capacitor (DC) snubber. For achieving higher efficiency, soft-switching technique is used to design the proposed converter. The converter topology analysis and design are described in detail. Results of simulation and experimental measurements are carried out to verify the performances of the proposed high voltage conversion ratio cascade boost converter under continuous conduction modes.
