Summary: | A four-quadrant power supply is difficult to realize high-frequency output through a conventional circuit of a switching device, a linear device is the best method for realizing high frequency, but the biggest trouble of a linear power supply is that the linear power supply works in a linear state, and the loss is large. The defect greatly limits the application of the linear device, so that the excellent high-frequency characteristic of the linear device is difficult to implement. The invention provides a technical scheme capable of effectively reducing the loss of a linear device, which comprises a four-quadrant linear output part, a multi-path output unit, a transformer and a transformer primary side circuit, realizes linear four-quadrant operation, controls the time-varying bus voltage through a voltage feedback cross-circuit of the linear output part, reduces the calorific value of an mos transistor, and improves the reliability of the mos transistor. The excellent characteristics of high frequency and l |
