摘要：This paper emphasizes the design of a DC-DC converter to produce high voltage from a low input DC voltage by using multiplier cells instead of a transformer. The low input DC voltage is converted to AC with the help of four switches operating in two different frequencies. Further, this AC voltage is given to the voltage multiplier cells for desired high output DC voltage. The output DC voltage produced has high efficiency, high voltage gain, low ripple, low switching losses and less noise. Two independent frequencies operate in this system, one is known as modulating frequency and the other is alternating frequency which work in high level and low level respectively. A prototype of the proposed model is constructed and the output is compared with the simulated model. The model is again reconstructed by a feedback control for constant output with variable input voltages.
