    摘要: A power-control device comprises an energy-import portion and an energy-export portion. The power-control device may additionally include a general processing and power supply circuit providing linear control of the power-control device's production of power to the load. The energy-import portion is coupled between a VLINE terminal and a load terminal, and is capable of importing energy to the load terminal during a first portion and a third portion of an alternating voltage VAC waveform. The energy-export portion is coupled between the load terminal and a NEU terminal, and is capable of exporting energy from the load terminal during a second portion and a fourth portion of the alternating voltage VAC waveform. The first, second, third and fourth portions of the alternating voltage VAC waveform are equal to a period of the alternating voltage VAC waveform and respectively are consecutive during the period of the alternating voltage VAC waveform. The power-control device provides variable power control to the load terminal in response to a variable on/off time of a PWM control signal.

    摘要: In a control apparatus, a controller performs comparison between a command voltage and a cyclic carrier signal to thereby perform one of pulse-width modulation upon each of first positive and negative peaks of the command voltage being within or identical to the corresponding one of second positive and negative peaks of the cyclic carrier signal, and single-pulse modulation upon each of the first positive and negative peaks of the command voltage being outside the corresponding one of the second positive and negative peaks of the cyclic carrier signal. The pulse-width modulation generates, for each cycle of the command voltage, plural drive pulses based on a result of the comparison. The single-pulse modulation generates, for each cycle of the command voltage, a single positive pulse and a single negative pulse for each cycle of the command voltage based on a result of the comparison.

    摘要: An apparatus includes an ON/OFF controller for regulating an output of a switched mode power supply by selectively enabling current conduction by a power switch within enabled switching cycles and disabling current conduction by the power switch within disabled switching cycles. The controller includes a logic block and a time-to-frequency converter. The logic block generates a drive signal that enables the current conduction by the power switch within respective enabled switching cycles and disables the current conduction by the power switch within respective disabled switching cycles. The time-to-frequency converter generates a variable-frequency clock signal that defines durations of the switching cycles, where the time-to-frequency converter increases a duration of a switching cycle in response to a decrease in duration of current conduction by the power switch in a previously enabled switching cycle.

    摘要: In an AC power supply apparatus, first and second switching circuits connected in series to an input terminal to which a DC input power supply is connected include first and second rectification elements, respectively. A capacitor, an inductor, and a capacitive load are equivalently connected in series to the second switching circuit. The capacitor is charged after the first switching circuit is turned on before the second rectification element is turned off and the charged capacitor is caused to discharge after the second switching circuit is turned on before the second rectification element is turned off. The above operations are periodically repeated. The voltage of the capacitive load is reversed with current flowing during the charge and the discharge of the capacitor to adjust the on and off periods of the first and second switching circuits in order to supply desired AC voltage to the capacitive load.

    摘要: A power converting apparatus comprises a DC-DC converter circuit that steps up or steps down an input voltage from a DC power supply, a DC-AC converter circuit that converts an intermediate voltage outputted by the DC-DC converter circuit to an alternate current, and a control circuit that controls the DC-DC converter circuit and the DC-AC converter circuit. The control circuit is provided with a circuit control unit that controls the DC-DC converter circuit so that the modulation factor, which is the amplitude ratio between a signal wave for manipulating the DC-AC converter circuit and the carrier wave therefor, will become a target modulation factor.

    摘要: An actual value (u.sub.ixRF) of a signal (i.sub.xRF) affected by harmonics may be corrected. A harmonic signal (u.sub.iF) superimposed on the signal (i.sub.xRF) is generated using a harmonic-free setting signal(u.sub.yR), a known pulse pattern (.alpha..sub.1, .alpha..sub.2, ..., .alpha..sub.5) stored in the memory of a modulator, and an equivalent model of the control system. The mean value (u.sub.iF) of this harmonic signal (u.sub.iF) is determined by a second integrating actual value acquisition device. The mean value (u.sub.iF) is subtracted as a correction value from the actual value (u.sub.ixRF), which is affected by errors. In this way, an errorfree actual value (u.sub.ixR) is obtained for a signal (i.sub.xRF), the harmonics of which are not filtered out in the actual value determination by means of an integrating actual value acquisition device.
