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 1):
A voltage conversion circuit comprising:\n a voltage conversion subcircuit comprising:\n a power transistor; \n a first energy storage element coupled to the power transistor; and \n a second energy storage element coupled to the power transistor; and \n a feedback loop coupled to the voltage conversion subcircuit and comprising:\n a sampling and amplification circuit configured to:\n sample a direct current voltage at a coupling end of the first energy storage element and the second energy storage element; and \n output a first signal; \n \n a feedback circuit configured to:\n sample the direct current voltage at the coupling end; \n obtain a sample signal; \n combine the sample signal with a triangular wave signal; and \n output a second signal; and \n \n a comparator circuit configured to:\n compare the first signal with the second signal; and \n generate a pulse width modulated (PWM) signal, the PWM signal controlling conduction or cutoff of the power transistor.
