CONVERTER CIRCUIT WITH ADJUSTABLE DC BUS VOLTAGE |
| 摘要 |
A method for controlling voltage of a DC bus in a converter circuit is provided. The method includes monitoring a duty cycle of a switch that connects a resistive circuit across the DC bus, the switch being closed when the DC bus voltage reaches an upper voltage value and opened when the DC bus voltage reaches a lower voltage value and altering the lower voltage value based upon the duty cycle of the switch. |

1. A method for controlling voltage of a DC bus in a converter circuit, comprising:
monitoring a duty cycle of a switch that connects a resistive circuit across the DC bus, the switch being closed when the DC bus voltage reaches an upper voltage value and opened when the DC bus voltage reaches a lower voltage value; and altering the lower voltage value based upon the duty cycle of the switch by decreasing the lower voltage value upon detection that an open time of the switch has decreased. |
