Embodiment Construction

[0022] In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. One skilled in the relevant art will recognize, however, that implementations may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures associated with computer systems, server computers and / or communication networks have not been shown or described in detail to avoid unnecessarily obscuring the description of the implementations.

[0023] Throughout the specification and claims that follow, unless the context requires otherwise, the word "comprise" is synonymous with "comprising" and is inclusive or open-ended (i.e., does not exclude additional, non-recited elements or method behavior).

[0024] Reference throughout this specification to "one implementation" or "an implementation" means that a particular feature, structure, o...

Abstract

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 andslope 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.

Description

technical field [0001] The present disclosure generally relates to controllers for power converters. Background technique [0002] A DC / DC converter is a power supply that converts an input DC voltage to a different output DC voltage. Such converters typically include a transformer electrically coupled through a switching circuit between a voltage source and a load. A converter known as a forward converter includes at least one main switch connected between a voltage source and the primary winding of the transformer to provide forward power transfer to the secondary winding of the transformer when the switch is turned on and conducting. Metal Oxide Semiconductor Field Effect Transistor (MOSFET) devices are typically used for one or more main switches. [0003] Power converter designs are often constrained by various requirements such as efficiency, input voltage range, output voltage, power density, and footprint. These limitations require certain performance trade-offs. ...
