摘要:
A modular converter (10) comprises a plurality of converter cells (36), which are connected in series on a first side and are connected on a second side, wherein each converter cell (36) comprises an AC-to-DC converter (40) connected to the first side and a DC-to-DC converter (42) connected to the second side. A method for controlling the modular converter (10) comprises the steps of: estimating the power transferred by the modular converter (10); comparing the transferred power with a threshold value; when the transferred power is bigger than the threshold value, operating the modular converter in a normal load operation mode (116, 122, 128); when the transferred power is smaller than the threshold value, operating the modular converter in a low load operation mode (114, 120, 126), in which the converter cells (36) are operated, such that switching losses are reduced with respect to the normal load operation mode.

A target power value determining unit (200) determines target power values Pc1 * and Pc2* such that a sum ΣPc* of target load powers as a sum of target load power Pc1* and target load power Pc2* does not exceed a sum ΣWin of allowable charging powers and a sum ΣWout of allowable discharging powers. In accordance with the generated target load power values Pc1* and Pc2*, switching commands PWM1 and PWM2 are generated. Consequently, an inverter executes a power conversion operation such that the powers exchanged between a main line ML and motor generators attain to the target load power values Pc1 * and Pc2*, respectively.

An ECU is mounted on a vehicle equipped with a converter that can boost a voltage of a power storage device storing electric power for obtaining driving force to output the boosted voltage to a drive load device. The ECU starts boosting at the converter upon satisfaction of at least any of a first condition that a boost request signal Req is received (that is, an output voltage request value of the converter exceeds a voltage Vb of the power storage device) and a second condition that output electric power P of the power storage device is higher than a value obtained by subtracting charge electric power ΔP transiently occurring at the start of boosting from rated electric power Wout (that is, it is predicted that output electric power P will exceed rated electric power Wout in response to the start of boosting).

A process and apparatus for reducing nitrogen oxide emissions in a genset comprising an engine and a generator and a shaft coupled to the engine and generator. The apparatus directs the generator to reduce load on the shaft while directing the engine to seek a steady state shaft speed for a desired energy transfer to the shaft when a shaft speed correction signal representing a shaft speed correction to reach the desired energy transfer meets a criterion.
