Abstract
A linear modulation voltage transformer circuitry includes a power stage unit, a voltage division unit, a linear modulation unit, an error amplifier, and a recursive controller. The power stage unit adapts an input voltage and outputs a first voltage to the voltage division unit, which outputs a divided voltage. The linear modulation unit receives the divided voltage, compares it with a control voltage, and outputs an error voltage signal to the error amplifier, which amplifies the error voltage signal as an error gain control signal. The recursive controller receives and modulates the error gain control signal and outputs the modulation error gain control signal to the power stage unit as a reference signal so as for the power stage unit to modulate the first voltage. Thus, the first voltage can be varied in real time via the linear modulation unit to meet load demands.
