摘要： PROBLEM TO BE SOLVED: To construct a chopper circuit C for compensating voltage unbalance that occurs between two series smoothing capacitors 12, 13 constructing a direct-current circuit of a high-speed control system, in a power conversion device in which a half-bridge power converter is used for a rectifier circuit A and an inverter circuit B. SOLUTION: The copper circuit C is provided with a voltage controller 35 and a pulse width modulator 39. The voltage controller computes the current command value for the chopper circuit C so that voltage unbalance between the two series smoothing capacitors 12, 13 is reduced. The current command value for the chopper circuit C and a current detection value of the chopper circuit C are compared to each other at constant sampling intervals. Then, a PWM signal is so generated as to invert the polarity of an error current, based on its positive/negative polarity. Turn-on/off of IGBTs 23, 24 is thereby determined so that the current command value for the chopper circuit C and the current detection value of the chopper circuit C agree with each other, at all times.

摘要： PURPOSE: To effectively display the function of a sodium sulfur battery to level electric power consumption by adopting a composition region, wherein a sulfur pole is corresponding to a two-phase region, as a normal service region to use the region other than the composition region in only emergency in the sodium sulfur battery. CONSTITUTION: In a sodium sulfur battery, a composition region, wherein a sulfur pole is composed of composition wherein the sulfur pole is neary corresponding to the two-phase region of sulfur and sodium pentasulfide, is adopted as a normal service region, and a region, wherein the sulfur pole is composed of composition other than the two-phase region of sulfur and sodium pentasulfide, is adopted as an emergency region. In using this battery, a region, wherein a discharge depth of the sulfur pole is to be 60-75%, is adopted as the normal service region to be used in a normal time, and a region, wherein a remaining discharge depth is 40-25%, is adopted as an emergency region to be inhibited from using it in the normal time but is used in only an emergency. A discharge depth region, wherein the capacity decrease of a cell in the repetition of charging/discharging for a long time can be neglected, is used as a normal service region, and a discharge depth region, wherein the capacity decrease of the cell is expected, is used as the emergency region.

摘要： PURPOSE: To simplify an output filter which reduces harmonic components. CONSTITUTION: In a PWM waveform generation circuit for a neutral-point clamp PWM inverter, carriers generated from two carrier-wave generators 4A, 4B and sine waves generated from a sine-wave generator 5 are level- compared by respective comparators 6A, 6B, outputs of both comparators are added by an addition circuit 6C, their phase is returned by a sign-inverting circuit 6D, and a PWM waveform which comprises a high level H, a low level L and a zero level 0 is generated. By this constitution, the carriers by both carrier-wave generators are changed into sawtooth waves. Thereby, a constitution in which the spectrum distribution of harmonic components contained in an inverter output concentrate near a frequency which is integral multiples of a carrier frequency and in which a specific frequency acts intensively on a specific frequency in an output filter to reduce the harmonic component, i.e., a filter constitution, is made simple, and the harmonic component is suppressed.
