Title:
POSITIVE/NEGATIVE POWER SUPPLY OUTPUT CONTROL APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/161663
Kind Code:
A1
Abstract:
A positive/negative power supply output control apparatus. The apparatus comprises a DC-DC power supply module (2), an energy storage inductor (L2), an energy-storage and energy-discharging capacitor (C8), a capacitor charging-discharging direction controlled bidirectional diode (D3), a positive power supply output module (3), a negative power supply output module (4), and a direct current power supply module (1). The output of the positive/negative power supply is controlled by the off and on of a switching transistor in the DC-DC power supply module (2), and then the output of positive and negative power supplies can be implemented simultaneously by using one DC-DC chip. The control apparatus and method are flexible and simple in control modes, can reduce design costs and power supply power consumption, and has a great prospect application and popularization prospect.
