The invention relates to a high-frequency linear generator analog power supply
system and a control method thereof. The
system comprises a
voltage transformation part, an impedance
simulation part, acontrol part and an execution mechanism, the
voltage transformation part adopts a
cracking transformer to form a
DC bus isolated H-bridge cascaded five-level circuit, and the output end of the voltagetransformation part is connected with the impedance
simulation part. The control end of the execution mechanism is connected with the
voltage transformation part and the impedance
simulation part, and the execution mechanism is further connected with the control part to achieve a local
control function. According to the method, a segmented asynchronous modulation method is adopted, multi-working-condition testing is carried out on output characteristics, per unit values of the output characteristics are calculated, and
curve fitting is carried out; and curves under different frequency division conditions are selected according to the magnitude of the load current and the subsection interval of the initial given frequency, and the output voltage is accurately controlled. According to the present invention, the
ripple waves of output voltage waveforms can be effectively reduced, and the output voltage quality and the output frequency precision are improved; and the
system and the methodhave the characteristics of short
response time, no need of feedback quantity, no
delay response and the like.
