Filed:

Aug 22, 2022

Appl. No.:

17/821257

Inventors:

- Kyoto, JP
John R. HOVERSTEN - Arlington MA, US
Yevgeniy A. TKACHENKO - Belmont MA, US

Assignee:

Murata Manufacturing Co., Ltd. - Kyoto

International Classification:

H02M 3/158
H02M 1/00

Abstract:

A circuit comprising a first capacitor configured to be charged to a voltage representing state information of a compensator, a second capacitor, a buffer circuit configured to charge the second capacitor to a voltage substantially equal to that of the first capacitor and a switching network configured to transition between a first state and a second state. When the switching network is in the first state, the second capacitor is charged to the voltage across the first capacitor. When the switching network is in the second state, the buffer circuit is disconnected from the second capacitor and the first capacitor and the second capacitor are connected in parallel.

International Classification:

H02M 3/07
H02M 3/158

Abstract:

A circuit configured to receive a first and second voltages and generate an output voltage, the circuit comprising: a first capacitor configured to charge to a voltage equal a difference between the first voltage and the output voltage; a second capacitor configured to charge to a voltage equal to a difference between the first voltage and the second voltage; and a plurality of conductive paths coupled to the first and second capacitors. In a first state, the conductive paths are configured to cause the second capacitor to charge to the voltage equal to the difference between the first voltage and the second voltage. In a second state, the conductive paths are configured to cause the second capacitor to be connected in parallel with the first capacitor to cause the first capacitor to charge to the voltage equal to the difference between the first voltage and the output voltage.
