Show moreThis invention relates to a power module for a plug-in hybrid electric vehicle including an integrated converter having a rectifier changing AC to DC, a DC/DC converter changing from a first voltage to a second voltage, and a battery storing electrical energy. The integrated converter operates in three modes 1) AC plug-in charging mode, 2) boost mode supplying power from the battery to the electrical bus and 3) buck mode supplying power from the electrical bus to the battery. The integrated converter utilizes the same single inductor during each of the three operating modes to reduce cost and weight of the system.

Show moreA method of controlling a DC/DC converter to regulate an output voltage from an input voltage source that varies from a fully-charged voltage to a discharged voltage. The method introduced improves the dynamic response of the converter during transients by switching between different converter topologies to spread out voltage spikes, which are an inevitable result of transients. The invention also can improve the efficiency of the DC/DC converter by replacing higher loss modes with combination modes.
