Abstract: A current control device and a power conversion system employing the current control device are provided. The current control device controls N power conversion unit(s), where N is a positive integer. The N power conversion units are connected in parallel when N is greater than 1. Each power conversion unit includes a signal input terminal and a current-controlled output terminal electrically connected to an external circuit. The current control device includes a first current sensor and an error compensator. The first current sensor samples a current flowing through the external circuit and acquires a sampling value. The error compensator receives the sampling value and a reference value and generates a compensation value accordingly, and outputs N current command(s) to the N power conversion unit(s) respectively according to the reference value and the compensation value.

Abstract: An optical transceiver module includes a first housing, a second housing, an engagement component, a conductive body, and a circuit board. The first housing has a first sidewall and a first groove. The first groove is closer to a central line of a major axis of the first housing than the first sidewall. The second housing is assembled with the first housing. The second housing has a second sidewall. The second sidewall is extended into the first groove. The engagement component has a first engagement portion. The first engagement portion is extended between the first sidewall and the second sidewall. The conductive body is disposed between the first groove and the second sidewall. The circuit board is disposed between the first housing and the second housing to perform photoelectric conversion. Therefore, the stroke of the engagement component can be fixed, and the electromagnetic interference can be reduced.

Abstract: An efficient control method for an isolated multilevel DC/DC resonant converter achieves a wide output voltage range with a narrow device switching frequency range, relative to the output voltage range and the device switching frequency range of the prior art. At any given time, a control circuit selects one of three different modulation schemes to operate the primary-side switching devices of the resonant converter based on at least one of output voltage, output current, input signal, and one or more external control signals. Together with a selected device switching frequency, the three modulation schemes generate different voltage waveforms to a primary-side transformer, which are coupled to the secondary-side to provide different output voltages.
