Voltage control device and method using sliding mode control of quantum series resonant converter

摘要

The present invention relates to a voltage control device using a sliding board control of a quantum series resonance resonant butter and a method thereof, and to a voltage control method using a conventional predictive current control method and a voltage control method using a sliding mode control method in a continuous time domain. The current must be detected, which is more difficult than the voltage detection of the resonant capacitor. In particular, the voltage control method using the predictive current control method is particularly complicated in the control circuit configuration and has a long voltage recovery time due to load variation. In the voltage control method using the sliding mode control method in the system or the voltage recovery time due to the load fluctuation is long and the stability analysis is difficult, the present invention in view of this point is to control the resonant capacitor voltage without the current as the control target To control the resonant capacitor voltage in the inner loop. Ride mode control facilitates the modeling of the converter for controller design and voltage detection of the resonant capacitor, and facilitates the construction of control circuits and system stability analysis.
