Abstract
The present invention discloses a frequency modulation type constant-voltage output power supply based on a high-voltage absorption circuit. The frequency modulation type constant-voltage output power supply is characterized by mainly comprising a transformer T, a diode D1, a triode VT5, a base trigger circuit respectively connected with the primary-side inductive coil L1 and the primary-side inductive coil L2 of the transformer T, and the like. According to the technical scheme of the invention, the input voltage is monitored, and the voltage is regulated in real time. Therefore, the voltage is maintained within a constant range. In this way, even when the commercial power fluctuates, the output voltage is ensured to be constant. The frequency of the voltage can also be regulated, so that the frequency of the output voltage is more stable. Therefore, the power supply can better supply power to electronic devices. Meanwhile, the induced voltage generated on the coil of the transformer during the outage period can be absorbed, so that the high-voltage breakdown of electronic components within the system can be prevented. Therefore, the safety performance of the frequency modulation type constant-voltage output power supply is improved.
