Abstract

The invention relates to the technical field of control circuits, and provides a voltage conversion circuit with a noise suppression function and power equipment, the circuit comprises a control element and a control program, and the control program controls the state of the control element according to a preset program; the control element comprises an original voltage unit, a substitute voltage power supply, a feedback unit, a suppression unit and a stabilization unit. The output end of the original voltage unit is connected with the input end of the feedback unit, the output end of the feedback unit is connected with the input end of the suppression unit, the output end of the suppression unit is connected with the stabilization unit, and the output end of the stabilization unit is connected with the power supply end; the output end of the feedback unit is connected with the input end of the substitute voltage unit, and the output end of the substitute voltage unit is connected with the stabilizing unit. According to the voltage conversion circuit, voltage fluctuation detection is realized, missing voltage signals are supplemented, fluctuation is suppressed, vibration noise caused by voltage fluctuation in the circuit is reduced, and the noise reduction performance of the voltage conversion circuit is improved.

Description

technical field [0001] The invention belongs to the technical field of control circuits, and in particular relates to a voltage conversion circuit and power supply equipment with a noise suppression function. Background technique [0002] The electrical board of the control equipment includes several electrical components, such as inductors and capacitors, transformers, etc., by designing these electrical components in the circuit to achieve the target control function. However, because the inductance and capacitance components have their own inductance properties, and the coil of the transformer itself also has inductance properties, so resonance will occur in the circuit, that is, the process of the inductance and capacitance itself continuously storing and releasing energy. Vibration causes noise in equipment, which not only affects the performance of the equipment, but also has a huge impact on people or things around the equipment that are not tolerant to noise. Theref...
