Web-browser plugin for consolidating requested disaggregated information

Systems and methods for providing peak current mode control (PCMC) for power converters using discrete analog components. A pair of complementary bipolar junction transistors may be used to set a maximum duty cycle for the power converter. PCMC may be achieved using a comparator that compares peak input current to an error feedback signal and terminates a pulse-width modulation (PWM) pulse when the peak input current exceeds the error feedback signal. A magnetic signal transformer may be used to establish a secondary side bias voltage supply, to return the error signal, and to drive an AC-coupled signal for a synchronous gate drive. A synchronous switch may be turned on when the main switch is turned off via an output winding of the flyback transformer and may be turned off by the trailing edge of a clock pulse from the magnetic signal transformer before the main switch is turned on.

Magnetic peak current mode control for radiation tolerant active driven synchronous power converters

Systems and methods for providing peak current mode control (PCMC) for power converters using discrete analog components. Peak current mode control functionality for latching, set, reset, clocking and slope compensation is provided via available analog components that provide improved performance, design flexibility, reliability, and radiation tolerance. Discrete analog components may include analog comparators, resistors, capacitors, diodes, etc.

Radiation tolerant, analog latch peak current mode control for power converters

A circuit for providing dynamic output current sharing using average current mode control for active-reset and self-driven synchronous rectification with pre-bias startup and redundancy capabilities for power converters. The circuit communicates a secondary side feedback signal to a primary side via a bidirectional magnetic communicator that also provides a secondary voltage supply. Pre-bias startup is achieved by detection of the output current direction and controlling the gate signals of synchronous rectifiers. The circuit permits dynamic current sharing via a single-control signal and automatic master converter selection and promotion.

Dynamic sharing average current mode control for active-reset and self-driven synchronous rectification for power converters

Systems and methods that provide control circuits having multiple sub-control inputs that control operation of a power electronics device (e.g., a power converter). Each of the multiple sub-control inputs are output from a separate sub-control circuit that includes a feedback circuit having an input tied to a common control node. The common control node is coupled to an input of a controller (e.g., a PWM controller). Outputs of each of the sub-control circuits are coupled to the common control node by a respective switch (e.g., diode, transistor, etc.) so that each of the sub-control circuits may be selectively coupled to the common control node to provide a control signal to a controller. Since components of each of the feedback compensations circuits are biased at a regulation voltage instead of a higher power supply voltage, the control circuit may switch between control modes with minimal delay.

Dynamic maneuvering configuration for multiple control modes in a unified servo system

Systems and methods are disclosed for providing over-voltage protection for power converters. An over-voltage protection loop includes an error amplifier that maintains an external reference voltage within a highly precise range that can be used to provide a highly precise output voltage from the over-voltage protection loop. The over-voltage protection loop may also include feedback impedance that delays the output of the over-voltage protection loop. The delay may prevent the over-voltage protection loop from being engaged due to voltage transients output from a main servo loop circuit that provides a nominal output voltage under normal operation, thus allowing the threshold voltage and output voltage of the over-voltage protection loop to be set close to the nominal output voltage of the main servo loop circuit.

Proactively operational over-voltage protection circuit

Systems and methods for providing a self-driven synchronous rectification circuit for an active-clamp forward converter which includes automatically enhancing synchronous MOSFETs and maximizing input voltage range. The gate signals for the synchronous MOSFETs are derived from a unipolar magnetic coupling signal instead of a bipolarized magnetic coupling signal. The unipolar signal is retained for fully enhanced driving of the MOSFETs at low line voltage and the unipolar signal is automatically converted to a bipolar signal at high line amplitude due to line variance to maximize input voltage range by utilizing non-polarized characteristics of the MOSFET gate-to-source voltage (Vgs). The circuit permits efficient scaling for higher output voltages such as 12 volts DC or 15 volts DC, without requiring extra windings on the transformer of the forward converter.
