Abstract

A system and method for controlling a power module are provided. The system includes a switch element that adjusts output of a power module, a driving signal generation unit that generates a switch ON signal and a switch OFF signal for the switch element, and a latch that is connected between the driving signal generation unit and the switch element and is configured to delay the switch ON signal generated by the driving signal generation unit by a preset delay time and transfer a delayed signal to the switch element. Additionally, a compensation unit is connected between the latch and the power module and is configured to adjust the output of the power module during the delay time by which the latch delays the switch ON signal.

Description

technical field [0001] The present invention relates to systems and methods for controlling power modules that improve the electromagnetic performance of power modules used in power supply equipment and also improve the accuracy of detecting switching arm shorts. Background technique [0002] Generally, components in various types of electrical and electronic products are powered by power to operate. Specifically, due to the influence of noise (including electromagnetic waves) caused by various reasons such as power instability or circuit instability, unnecessary power consumption occurs, and the service life of electronic and electrical products is shortened. [0003] The causes of such noise can be classified into three categories. 1. Intrinsic noise sources, including thermal noise due to the inherent properties of physical systems, etc. 2. Man-made noise refers to the noise generated by equipment, such as motors, switches, digital devices or antennas. 3. Noise from na...
