Title:
CONTROL DEVICE AND METHOD FOR POWER AMPLIFIER, AND MAGNETIC SUSPENSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/247302
Kind Code:
A1
Abstract:
Disclosed in the present application are a control device and method for a power amplifier, and a magnetic suspension system. The power amplifier comprises an upper diode and a lower diode. The upper diode comprises more than one switching transistor, and the lower diode comprises more than one switching transistor. The control device for a power amplifier comprises: a control unit configured to determine a PWM signal of the power amplifier and output the PWM signal, wherein there is more than one PWM signal; a chip select unit configured to perform signal multiplexing on at least one PWM signal among the more than one PWM signals to obtain at least two PWM multiplexed signals of the at least one PWM signal, so as to use one PWM multiplexed signal to perform drive control on the switching transistor in the upper diode or the lower diode by means of a drive circuit of the switching transistor in the upper diode or the lower diode.
