摘要： A power regulator (30) is provided which employs a resonant circuit (32) and permits regulation between a certain maximum value and zero. A series resonant circuit is adjusted to regulate power by adjusting the correspondence between the resonance frequency and the frequency of the voltage source (31) such as an AC source delivering a sine wave or a square wave. Further, the output voltage is regulated to be lower than the AC source (31) when output current is zero. A capacitance (C2) is connected in parallel with the output of the power regulator (30) to form a second resonant circuit with the inductance (L1) of the series resonant circuit (32). A method of power regulation is also contemplated.

摘要： It is a problem of the present invention to provide an inverter device whose current detection precision is improved by checking variations in the distribution of current flowing in a shunt resistor without using a separate member. In a printed board (40) of an inverter device (20), a first conductive pattern component (51) connected to a shunt resistor (31) includes a first central region (510), a first right-side protruding region (511) that juts out on the right side from the first central region (510), and a first left-side protruding region (512) that juts out on the left side from the first central region (510). The ratio SA2/SA1 of the area SA2 of the first left-side protruding region (512) to the area SA1 of the first right-side protruding region (511) is set in the range of 0.6 to 1.6, whereby variations in the distribution of current flowing in the shunt resistor (31) can be checked.

摘要： A high-frequency ac-dc power converter takes an input ac signal and converts it to an output dc signal. The converter has at least two front-end rectifier diodes arranged as a full wave rectifier of the input ac signal. A first inductor positioned at the output of the full wave rectifier. An output capacitor is connected across a load for the converter. There are at least one additional inductor and one additional capacitor. A switching circuit selectively forms different (LC) resonant circuits with the inductors and capacitors during a cycle of the input ac signal to form a dc-dc power converter.

摘要： A voltage source converter includes a converter limb extending between DC terminals and having limb portions separated by an AC terminal, the DC terminals being connectable to a DC electrical network and the AC terminal being connectable to an AC electrical network. Each limb portion includes at least one switching element and a chain-link converter including a series-connected modules, each module including at least one switching element and at least one energy storage device combining to selectively provide a voltage source. The chain-link converter is connected to the AC terminal, and the switching element(s) of each limb portion is switchable to switch the chain-link converter into and out of circuit with the corresponding DC terminal. The voltage source includes a control unit which coordinates the switching of the switching elements of the limb portions and the switching element(s) in each module of the chain-link converter.

摘要： The present invention relates to a device (1) for detecting a failed rectifier in three-phase AC/DC converter having its AC side connected to a three-phase AC source (90) and its DC side connected to a DC load (50), the AC/DC converter including a rectifier circuit (30) comprising at least three legs (31, 31', 31"), each of the legs (31, 31', 31") connected to a corresponding AC phase (40) and including at least one rectifier (32, 34, 32', 34', 32", 34"), the device (1) including a measuring unit (20) for measuring and sampling AC current for each of the phases and a calculating unit (10) configured to estimate an instantaneous DC current based on the measured instantaneous AC currents during one period of the power supply frequency. The calculating unit (10) is further configured to calculate a ripple value of the estimated instantaneous DC current, determine if the calculated ripple value exceeds a pre-defined threshold value, initiate an alarm accordingly, calculate a rectifier status value based on a maximum instantaneous AC phase current and a minimum instantaneous AC phase current during the same one period, and determine, for each of the legs, if the rectifier in the leg has a non-conducting fault based on the calculated rectifier status value.

摘要： A two-wire load control device prevents load malfunctioning, such as erroneous emission of an LED, due to a leak current, even when loads not taking countermeasures against noise are connected. The load control device is connected in series between a commercial power source and a load and an off power supply for ensuring an inner power supply at the time of turning off the load is provided with capacitors, which are switched to be connected in series or parallel, based on an input voltage. The control device makes the capacitors repeat charging and discharging, and a power discharged from the capacitors is used as the inner power supply, thereby reducing standby power requirement of the load control device at the time of turning off the load.
