And the current stability requirements better than 10ppm. Therefore, the power supply is mostly used in the mode of module series-parallel. However, during actual commissioning, the power supply often does not run at rated current. If the power supply is running at less than 30% of the rated current, the power output current stability will drop sharply. This topic designed a set of digital controller for multi-module serial-parallel control. The digital controller can automatically adjust the number of input modules according to the current setting, and can automatically allocate the required PWM number of the module. While taking into account the synchronization between the various modules, Ensure the power supply is always running at an optimal working condition. Through a special AD conversion hardware design and advanced closed-loop controller algorithm, the digital controller can provide up to 20 high-resolution PWM signals to drive power conversion devices.
