A flyback power supply method and apparatus is disclosed. An apparatus according to aspects of the present invention includes an energy transfer element having a primary winding and first and second output windings. The first and second output windings are coupled to produce first and second output values, respectively. A primary switch is coupled to the primary winding. A control circuit is coupled to the primary switch to regulate a sum of the first and second output values. A steering circuit having first and second output switches is also included. The first and second output switches are coupled to the first and second output windings, respectively, to regulate a ratio of the first output value to the second output value. The first output switch is coupled to block current through the first output winding and the second output switch is coupled to block current through second output winding. At least one of the first and second output switches is coupled to be closed when the primary switch is opened.

This relates to an apparatus and method for selectively adding a capacitance to an input of a power converter of a power conversion system. A power conversion system may selectively introduce additional input capacitance in response to an input voltage. In one example, a power conversion system operates in a first mode (dimming mode) and engages a selective capacitor circuit to introduce additional capacitance to an input of a power converter. In a second mode (non-dimming mode), the power conversion system disengages the selective capacitor circuit from the input of the power converter.

An electric vehicle charging station that uses a liquid cooled charging cable is described. The charging station includes a charging port that is configured to connect to a liquid cooled charging cable. The liquid cooled charging cable includes a cooling loop where a return side of the cooling loop is a warm side. The charging station includes a heat exchanger that transfers heat from the warm side of the cooling loop. The charging station includes a pump to pump a cool side of the liquid through the cooling loop. The charging station includes a module that causes the following to be performed in response to a startup sequence of the electric vehicle charging station: iteratively perform operations of operating the pump at increasing speeds and measuring corresponding pressure output until the speed of the pump is at its normal capacity.

Dynamic allocation of power modules for charging electric vehicles is described herein. The charging system includes multiple dispensers that each include one or more power modules that can supply power to any one of the dispensers at a time. A dispenser includes a first power bus that is switchably connected to one or more local power modules and switchably connected to one or more power modules located remotely in another dispenser. The one or more local power modules are switchably connected to a second power bus in the other dispenser. The dispenser includes a control unit that is to cause the local power modules and the remote power modules to switchably connect and disconnect from the first power bus to dynamically allocate the power modules between the dispenser and the other dispenser.

A first dispenser receives a request to initiate charging service for charging an electric vehicle. The first dispenser determines an amount of power that is available for the charging service for charging the electric vehicle including determining an availability status of multiple power modules that are located in the first dispenser and a second dispenser. The first dispenser determines whether the available amount of power is enough to meet a requested or determined amount of power draw of the electric vehicle. If the available amount of power is not enough to meet the requested or determined amount of power draw of the electric vehicle, and if there is at least one of the power modules that is available, the first dispenser requests allocation of the available power module and charging service commences.

A power converter controller includes a drive circuit to generate a drive signal to control switching of a power switch. The drive circuit generates the drive signal in response to a current sense signal, a current limit signal, a frequency skip signal, and a hold signal. A current limit generator generates the current limit signal in response to a load. A frequency detection circuit generates the frequency skip signal in response to the drive signal to indicate when an intended frequency of the drive signal is within a frequency window. The current limit signal remains fixed for at least a switching cycle when the intended frequency is within the frequency window. A first latch generates the hold signal to control the current limit generator to hold the current limit signal. The first latch generates the hold signal in response to the frequency skip signal and a feedback signal.

A controller for use in a power converter that includes a current limit generator coupled to receive a feedback signal representative of an output of the power converter and generate an initial current limit signal. The controller includes a modulation circuit coupled to output a modulation signal which is a percentage of the initial current limit signal. An arithmetic operator is coupled to receive the initial current limit and selectively receive the modulation signal and output a current limit. A comparator is coupled to receive a current sense signal representative of a switch current conducted by a primary switch. A drive circuit is coupled to generate a drive signal to control switching of the primary switch to regulate the output of the power converter in response to the comparator output signal, and the drive circuit turns off the primary switch when the switch current has reached the current limit.
