Latest Patents
Mueller's latest patents include a device for measuring a current through a choke and a method for operating this device. The invention relates to a device designed for measuring current through a choke of a voltage converter. It comprises an integrator circuit, an amplifier circuit, and an NTC resistor. The amplifier circuit features both inverting and non-inverting amplifier input connections, along with an amplifier output connection. The non-inverting amplifier input connection receives an amplifier input signal based on the integrator output signal. A voltage signal that characterizes the current through the choke is applied at the amplifier output connection. The NTC resistor is strategically placed in the feedback path of the amplifier circuit between the inverting amplifier input connection and the amplifier output connection.
Another significant patent by Mueller is an activation apparatus for a galvanically decoupled direct voltage converter equipped with a synchronous rectifier. This invention includes a signal generating device that produces control signals for the switch devices of the synchronous rectifier and a reference current signal. A first comparator device is coupled to the signal generating device to detect the secondary-side output current of the synchronous rectifier, compare it to the reference current signal, and generate a current control signal based on this comparison. Additionally, a pulse width modulation device is integrated to generate pulse width modulated activation signals for the switch devices of the synchronous rectifier, utilizing the control signals and the current control signal.
