Title:
HIGH-POWER ADJUSTABLE HIGH-FREQUENCY FRACTIONAL ORDER CAPACITOR HAVING ORDER GREATER THAN 1 AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/023919
Kind Code:
A1
Abstract:
A high-power adjustable high-frequency fractional order capacitor having an order greater than 1 and a control method thereof. The fractional order capacitor comprises an alternating current input module (1), a coupling impedance (2), a high-frequency alternating current controlled voltage source (3), an alternating current input and sample module (4) and a controller (5). The controller (5) generates corresponding control signals according to an input voltage signal and an input current signal collected by the alternating current input and sample module (4) to control the output voltage of the controlled voltage source (3), so that an input current and an input voltage satisfy the relation between the current and voltage of the fractional order capacitor. The adjustable high-frequency fractional order capacitor can be operated when an input voltage, i.e., the voltage of the fractional order capacitor, is at high frequency; and the obtained relation between an input current and input voltage at a required operating frequency is completely consistent with that defined in the fractional order capacitor having an order greater than 1. The order and capacitance values of capacitors having different fractional orders can also be flexibly adjusted and obtained by adjusting parameters of the controller. A controlled voltage source having different power levels can also be selected to adapt to different power application occasions.
