Parts and power efficient single stage architecture
Our power technology supports bidirectional power flow to isolated AC and DC ports in a single stage.
Comparable prior art architectures require multiple stages to realize similar functionality.
Our novel architecture translates to opportunities for parts count reduction and improvement in efficiency for AC coupled converters with isolated bidirectional DC energy storage, and opportunities for improved efficiency and performance of DC/DC power converters. The single stage power supply technology has beneficial characteristics across a number of illustrated example applications.
Depending on application specific requirements, implementations may emphasize characteristics such as: power factor corrected isolated AC and DC connectivity and bidirectional energy storage, accessible low parts count distributed power solutions, reduced weight and volume solutions with efficient power and magnetic material utilization, and robust and efficient low noise bidirectional power regulation. Please see the technical library and contact links on our solutions page for more information.
While an exact comparison to prior art will depend on the specific application, a potential relative comparison to a prior art solid state transformer with comparable functionality (and an AC/DC converter with dashed elements omitted) is illustrated in the following figure to show proportional material benefit associated with reduced active bridge and power magnetic components. Our technology applied to a single stage solid state transformer application results in elimination of two active bridges relative to the prior art example, with further related reductions associated with independent controllers, bridge drivers, and mechanical interfaces. Transformer and filter components may further be integrated using our technology to reduce weight and material cost.
Our technology balances efficiency and implementation favorably relative to selected classic DC/DC power converter architectures. The following table illustrates nominal characteristics of modern power technologies such as: bidirectional power transfer, load voltage regulation, efficient operation, and filter material integration.
Our patented technology employs synchronous average harmonic control to synthesize advantages of multiple classic power supply architectures together including: a soft switching (efficient) design regime, straightforward voltage control and bidirectional power transfer, and magnetic filter integration. The novel control method results in high performance DC/DC power conversion and is an enabling technology which allows for superposition of multiple functions in a single stage.
