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.

Abstract: The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased.
