Abstract

The invention provides an inverter power supply circuit. Fast conversion from the direct current to the alternating current is achieved by the matching of a field-effect tube Q1 and a field-effect tube Q2, the breakover current of the Q2 is directly lowered through the Q1 before the Q2 is connected, and thus a winding on the right side can generate induced electromotive force. The polarity of the voltage on the left side is positive and the polarity of the voltage on the right side is negative. The current arrives at a resistor R4 on the left side through the winding intersection, and then arrives at the tail portion of the winding after reaching the grid electrode of the Q2, and hence a circuit is formed. In this way, the Q2 is connected, the starting of oscillation is achieved from the Q, and therefore the problem of overlong delay is solved. By means of the inverter power supply circuit, and fast oscillation starting can be achieved; besides, the problem that currents are too high under the condition of too-high load power is solved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an inverter power supply circuit. 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 shortcomings of the prior art described above, the purpose of the present invention is to provide an inverter power supply circuit for solving the problem of how to overcome the problem of excessive current under high power, and how to realize fast DC-to-AC conversion and avoid excessive delay problem of the situation. [0004] In order to achieve the above object and other related objects, the presen...
