Abstract

The invention discloses a UPS bypass driving unit, which comprises a DSP control module, a bypass driving enabling module, a DSP operation detection module and a bypass driving module, wherein the DSPcontrol module is used for sending a first control signal to the bypass driving enabling module and sending a second control signal to the DSP operation detection module; the bypass driving enablingmodule is used for sending a driving starting enabling signal to the bypass driving module when receiving the first control signal; the DSP operation detection module is used for sending a DSP abnormal enabling signal to the bypass driving module when detecting that the second control signal is abnormal; and the bypass driving module is used for forming a driving signal for starting bypass outputand stopping inversion output at the output end of the bypass driving module when receiving the driving starting enabling signal and the DSP abnormal enabling signal. The invention further discloses aUPS bypass driving system. The UPS bypass driving system comprises more than two UPS bypass driving units and a parallel operation switch control module. The UPS bypass driving unit is used for stably switching to a bypass output state in case of an operation fault so as to reliably supply power.

Description

technical field [0001] The invention relates to the technical field of integrated electronic circuits, in particular to a UPS bypass drive unit and a UPS bypass drive system. Background technique [0002] The existing UPS power supply generally includes a main circuit connected in series between the mains and the load and a bypass connected in parallel with the main circuit. Voltage constant frequency circuit, which is mainly used to charge the battery by the mains, and then provide a stable and uninterrupted power supply for the load by the battery after inverter; the bypass is mainly used when the main circuit fails or the load is overloaded The mains and the load are connected downwards, so that the mains can directly supply power to the load, thereby ensuring reliable power supply of the UPS power supply. [0003] The UPS power supply usually sets the DSP control module to realize the closure of the digital automatic control bypass switch, which is used to switch from t...
