The inverter power supply uses the crystal gauge circuit to transform the DC power into AC power. This reverse process corresponding to the rectifier is defined as the inverse.For example, the electric locomotive of the crystal tube is used to operate the DC motor as a generating mechanism during the uphill, and the position of the locomotive can be transformed into electrical energy and sent it to the AC power grid.

Principles of inverse power supply
1. Working principle of full -control inverter: In order to be the main circuit of a single -phase output of single -phase output, the AC component uses IGBT tube Q11, Q12, Q13, Q14.And PWM pulse width adjustment controls the turnover or end of the IGBT tube.When the inverter circuit is connected to the DC power supply, it is turned on by Q11, Q14, and the Q1 and Q13 are output by the positive electrode of the DC power supply.To the negative electrode of the power supply.When the Q11 and Q14 are dead, Q12 and Q13 are turned on, and the current feels from Q13 and the primary coil of the transformer at the power supply. The Q12 feels Q12 back to the negative power of the power supply.At this time, on the primary coil of the transformer, positive and negative variables have been formed. Using high -frequency PWM control, the two pairs of IGBT tubes are alternately repeated to generate AC voltage on the transformer.Due to the role of LC AC filter, the output end forms a sine wave AC voltage.When the Q11 and Q14 are off, in order to release the storage energy, the second -level tube D11 and D12 are connected at the IGBT to return the energy to the DC power supply.
