    摘要： Embodiments of the present disclosure relate to the field of electrical technologies and disclose an I-V converting module. The I-V converting module includes: a current output sensor, an I-V transforming circuit, a sampling and holding circuit, a source follower, a loop switch, and a bypass circuit. A drain of the source follower is connected to an input/output end of the sampling and holding circuit, a source of the source follower is connected to an input end of the I-V transforming circuit and an output end of the current output sensor, and a gate of the source follower is connected to an output end of the I-V transforming circuit via the loop switch. The gate of the source follower further is connected to the bypass circuit. When the loop switch is closed and the bypass circuit is disabled, a feedback loop formed by the source follower, the I-V transforming circuit and the loop switch is conducted, and the I-V converting module enters into a sampling setup stage. The present disclosure greatly accelerates a setup speed of the sampling and holding circuit, thereby increasing the converting rate of the I-V transforming circuit.

    摘要： A drive circuit for driving an electro-optical device like an optically switchable glazing, e.g. a glass panel provided with a PDLC or SPD layer, comprises a set of input terminals for receiving an alternating input voltage at a first frequency; a set of output terminals for supplying an alternating output voltage at a second frequency; a control circuit generating a control signal dependent on an input signal, the input signal representing a charge state of the electro-optical device; and a current-direction circuit for controlling a current-flow direction of an electrical current in response to the control signal. The control circuit and the current-direction circuit are thereby configured to control the second frequency such that the electro-optical device is prevented from degradation, while keeping an energy consumption low.
