Abstract

The invention discloses a control method of a switching power supply device. The control method has the following steps: using a pulse modulation signal to control a switching power supply device; measuring an output signal of the switching power supply device; The comparison signal is multiplied and divided by a modulation gain to generate a reference input signal; a duty cycle of the pulse modulation signal is adjusted according to the reference input signal.

Description

technical field [0001] The present invention relates to a control method of a switching power supply apparatus, especially a control method based on an output signal of the switching power supply apparatus. Background technique [0002] With the advancement of technology, most of the equipment and facilities currently require electricity. Some of these special equipment or facilities often require power supplies of corresponding specifications. For example, a data center consumes a lot of power. Therefore, in order to save energy, today's data centers often adopt an architecture design that directly draws energy from high-voltage electric towers to avoid increasing losses through layer-by-layer energy conversion. [0003] In the field of power conversion of high-voltage power supplies, the Input Series Output Parallel (ISOP) architecture is currently commonly used to supply power from multiple power supplies. However, when the input signal or output signal of one of the p...
