Abstract :
This paper proposes a novel self-oscillating,
boost-derived (SOBD) dc-dc converter with load regulation.
This proposed topology utilizes saturable cores (SCs) to offer
self-oscillating and output regulation capabilities.
Conventionally, the self-oscillating dc transformer (SODT)
type of scheme can be implemented in a very cost-effective
manner. The ideal dc transformer provides both input and
output currents as pure, ripple-free dc quantities. However,
the structure of an SODT-type converter will not provide
regulation, and its oscillating frequency will change in
accordance with the load. The proposed converter with SCs will
allow output-voltage regulation to be accomplished by varying
only the control current between the transformers, as occurs
in a pulse-width modulation (PWM) converter. A control network
that combines PWM schemes with a regenerative function is used
for this converter. The optimum duty cycle is implemented to
achieve low levels of input- and output-current ripples, which
are characteristic of an ideal dc transformer. The oscillating
frequency will spontaneously be kept near-constant, regardless
of the load, without adding any auxiliary or compensation
circuits. The typical voltage waveforms of the transistors are
found to be close to quasisquare. The switching surges are
well suppressed, and the voltage stress of the component is
well clamped. The turn-on/turn-off of the switch is
zero-voltage switching (ZVS), and its resonant transition can
occur over a wide range of load current levels. A prototype
circuit of an SOBD converter shows 86% efficiency at 48-V
input, with 12-V, 100-W output, and presents an operating
frequency of 100 kHz
