Abstract

The invention provides an inverter power supply circuit capable of preventing too high load power. Rapid transformation between DC to AC is realized through cooperation between a field effect transistor Q1 and a field effect transistor Q2, before the Q2 is conducted, the Q1 directly draws low conduction currents of the Q2, in such a way, a winding at the right side generates an induction electromotive force, the polarities of voltages are positive at the left and negative at the right, currents flow from the intersection point of the winding to a resistor R4 at the left, to the grid of the Q2 and then to the tail of the winding so as to form a loop, thus the Q2 is conducted, oscillation starts from Q, and the problem of too long delay is avoided. The inverter power supply circuit provided by the invention can realize rapid start of oscillation and overcomes the problem of too high currents caused by too high load power.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an inverter power supply circuit capable of preventing excessive load power. Background technique [0002] It is a common thing in the production process to convert the DC power supply to AC power to supply power to the lamp. However, in some high-power loads, how to overcome the problem of excessive current under high power, and how to achieve fast DC-to-AC and avoid delays If it is too long, this is a problem that needs to be overcome by those skilled in the art. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an inverter power supply circuit with protection against excessive load power, which is used to solve the problem of how to overcome the problem of excessive current under high power and how to realize fast DC Issues with switching exchanges and avoiding situations...
