Abstract:
A voltage conversion circuit and method, and a multiphase parallel power system, where in the voltage conversion circuit, a feedback circuit provides a frequency-controllable feedback ripple signal. Therefore, the voltage conversion circuit has a controllable operating frequency, and a frequency requirement of a load may be met. Compensation does not need to be performed in a hysteresis mode, and therefore the hysteresis mode has a fast-speed response. The operating frequency is fixed. Therefore, the voltage conversion circuit in the embodiments may be applied to the multiphase parallel power system such that the multiphase parallel power system is applicable to an application scenario with a large load current.

Claim (Index 19):
A voltage conversion method, applied by a feedback loop comprising a sampling and amplification circuit, a feedback circuit, and a comparator circuit, the method comprising:\n sampling, by the sampling and amplification circuit, a direct current voltage at a coupling end of a first energy storage element and a second energy storage element of a voltage conversion subcircuit; outputting, by the sampling and amplification circuit, a first signal based on the direct current voltage; obtaining, by the feedback circuit, a sample signal by sampling the direct current voltage at the coupling end of the first energy storage element and the second energy storage element of the voltage conversion subcircuit; combine, by the feedback circuit, the sample signal with a triangular wave signal to output a second signal; and compare, by the comparator circuit, the first signal with the second signal to generate a pulse width modulated (PWM) signal, the PWM signal controlling conduction or cutoff of a power transistor of the voltage conversion subcircuit.
