Abstract

A control system includes a control device adapted to be connected to a live line and a neutral line that transmit a grid power, and to a load via a first power line and a second power line. The control device includes: a first switch adapted to be connected between the live line and the first power line; a second switch adapted to be connected between the neutral line and the second power line; a coupler adapted to be connected to the first power line, receiving a communication signal, and coupling the communication signal to the first power line; and a controller controlling the first and second switches to synchronously alternate between an ON state and an OFF state, and outputting the communication signal to the coupler when the first and second switches operate in the OFF state.

Abstract

An ultra high voltage regulator includes a rectifying circuit, a first transistor, a second transistor, an output capacitor, a bootstrap diode, a bootstrap capacitor, and a gate driver circuit. The ultra high voltage regulator converts a received alternative current into a direct voltage to an electrical component. The ultra high voltage regulator is capable of providing a larger current becomes more compact and thinner in size without cooperating with a mass transformer/high voltage capacitor, which satisfies the request for miniaturization of the electrical components.

IPC Classes  ?

• H02M 7/217 - Conversion of AC power input into DC power output without possibility of reversal by static converters using discharge tubes with control electrode or semiconductor devices with control electrode using devices of a triode or transistor type requiring continuous application of a control signal using semiconductor devices only

An ultra high voltage regulator for converting includes a rectifying circuit, a first transistor, a second transistor, an output capacitor, a first resistor, a second resistor, and a third resistor. The ultra high voltage regulator converts a received alternative current into a direct voltage to an electrical component. The ultra high voltage regulator capable of providing a larger current becomes more compact and thinner in size without cooperating with a mass transformer/high voltage capacitor, which satisfies the request for miniaturization of the electrical components.
