Abstract:
This article analyzes the operational sub-modes and design of
integrated boost-flyback DC high step-up conversion converter circuit,
which transforms a 24-volt input DC power supply into a 360-volt highvoltage
output side. The circuit state-of-the-art is designed to function in
Integrated with the boost and flyback circuit during the quasi-resonance
operating conditions. The power section's transition time, using a single
switch, is established as the zero-current transition (ZCT) at a fixed
switching frequency of 96 kHz. The results of the simulation show that
under full load operation, the input and output powers are 135 watts and
122 watts, respectively. The output voltage is configured as a voltage
multiplier with a series capacitor. The examination of significant
relationships is offered to validate the accuracy of the model and indicate
the theory's reliability.
