| 20100097828 | Interleave control power supply device and control circuit and control method for the power supply device - A two-phase critical interleave PFC boost converter, includes a master-side control circuit configured to critically control a first switching element based on a master signal; and a slave-side control circuit configured to critically control a second switching element based on a slave-signal with a phase difference of 180° from the master signal. In the PFC boost converter, an off period generator of the master-side control circuit feeds an M_ON signal which is the same in waveform as the master signal to an on phase controller of the slave-side control circuit, and the slave-side control circuit determines the rising timing of the slave signal from the rising time of the master signal. | 04-22-2010 |
| 20110267854 | POWER CONVERTER WITH DUAL RING NETWORK CONTROL - A method for providing electric power to a power system includes receiving, at a slave node of a power converter having a plurality of slave nodes, a first synchronization signal via a first communication channel, the first synchronization signal purporting to represent a master timing characteristic of a master control node of the converter; receiving, at the slave node of the converter, a second synchronization signal via a second communication channel, the second synchronization signal purporting to represent a master timing characteristic of the master control node of the converter; synchronizing an internal timing characteristic of the slave control node with the master timing characteristic of the master control node using the first synchronization signal; determining that the first synchronization signal is invalid; and synchronizing an internal timing characteristic of the slave control node with the master timing characteristic of the master control node using the second synchronization signal. | 11-03-2011 |
| 20120140534 | POWER CONVERSION SYSTEM AND COMMUNICATION ADDRESS SETTING METHOD - There is provided a power conversion system, and a photovoltaic inverter includes a communication unit that broadcast-transmits a setting request signal of a predetermined communication address. The photovoltaic inverter includes a display unit that displays the predetermined communication address indicated by the setting request signal, and an address setting unit that generates a setting completion signal indicating that the predetermined communication address has been set as the communication address of the photovoltaic inverter if an input accepting unit accepts an input such that the predetermined communication address is set. An address management unit of the photovoltaic inverter generates a setting request signal indicating a communication address other than the predetermined communication address if the setting completion signal for the predetermined communication address is received. | 06-07-2012 |
| 20120182773 | METHOD FOR SHARING INPUT AND OUTPUT PORTS - Disclosed is a method for sharing input/output ports among inverters. A sharing method by a master inverter according to the present disclosure is such that data to be outputted to an output port of a slave inverter is transmitted to the slave inverter where data inputted to input port of the slave inverter is received. Furthermore, a sharing method by the slave inverter is such that data transmitted along with a request frame is outputted to an output port in case of receiving the request frame requesting use of the output port from the master inverter, where data used by the master inverter among data received from input port is transmitted to the master inverter. | 07-19-2012 |
| 20130141952 | PARALLEL INVERTER DEVICE AND METHOD FOR CONTROL THEREOF - Inverters connected in parallel each include a power converter that carries out a direct current to alternating current conversion and supplies voltage to a motor, and a control unit, where one of the inverters is a master inverter and the control unit computes a voltage command value for the power converter in the one inverter, while the other inverter is a slave inverter and the power converter in the slave inverter is driven by the voltage command value, a transmission means transmits the voltage command value, and the control unit of the master inverter includes a delay device that delays the voltage command value by a transmission time needed when transmitting a computed voltage command value to the slave inverter, and provides the voltage command value delayed by the delay device to the power converter of the master inverter. | 06-06-2013 |
| 20130201737 | OFF-GRID MASTER-SLAVE SOLAR INVERTER SYSTEM AND METHOD THEREOF - A control method of an off-grid master-slave solar inverter system includes powering on the off-grid master-slave solar inverter system; a controller controlling a first inverter and a second inverter to prepare to output pulses corresponding to a first series number and pulses corresponding to a second series number, respectively; only the first inverter outputting a pulse corresponding to a first number of the first series number; and the controller controlling the first inverter to output a first alternating current voltage and the second inverter to output a second alternating current voltage with a frequency of the first alternating current voltage after a first predetermined time. | 08-08-2013 |
