1. A switched mode power supply including:
- interconnected first and second half bridge units; and
a control circuit configured to operate the interconnected first and second half bridge units as a full bridge converter,wherein the first and second half bridge units are separable units configured to be interconnected to one another and wherein the first and second half bridge units and the control circuit are configurable to a first configuration wherein the control circuit operates at least one of the first and second half bridge units as a half bridge converter and a second configuration where the control circuit operates the first and second half-bridge units together as a full bridge converter.

Abstract
A switched mode power supply allowing a half bridge converter to be use alone or in combination with another converter to form a full bridge converter. A common controller may be used for either half bridge or full bridge configurations. The modular approach simplifies design for a range of power supplies and reduces costs.

16. A method of producing a switched mode power supply comprising:
-
providing first and second separable half bridge units that are configured to be electrically interconnected; providing a control circuit configurable to individually operate at least one of the first and second half bridge units as a half bridge converter in a first configuration and to operate the first and second half bridge units together as a full bridge converter; connecting the first and second half bridge units so as to form a full bridge converter; and connecting the control circuit to the connected first and second half bridge units in such a manner that it operates the connected first and second half bridge units as a full bridge converter. - View Dependent Claims (17, 18, 19, 21)
