Microgrids, Solar, and Storage for Smart Grids and Transportation

Mission

We provide OEMs and SIs (System Integrators) with a competitive advantage within their own markets by enabling

tailored power electronics systems.

We do this by developing equipment which enables customized solutions, freeing SIs and OEMs from the generic

equipment which is available on the market today.

Converting DC to AC to connect battery banks to the utility grid

Converting AC (grid) to DC to charge a vehicle, or controlling a high-speed traction motor

EPC Grid Converter

Battery Bank

EPC makes power conversion products

BackgroundEPC was founded in 2010, with a mission to be

wholly focused on the development and production of engineered power electronics systems at greater

than 100kW (130HP).

From inception, the company has focused on building its core technology to gain leverage in

diverse market segments.

EPC was “boot-strapped” and primarily funded by its customers and has grown to multiple markets and

product lines.

DG-LC12/3 – EPC’s LC12/3 line provides 3-wire control for the highest power applications. 30v – 1250v DC input is provided across the top 2 terminals. The LC12/3-5 can manage up to 500kW of power and the LC12/3-7 can provide up to 700kW in the same form factor.

MG-LC12/6 - EPC’s LC12/6 line provides 4-wire control with two DC inputs for microgrid power applications. 30v – 1250v DC input is provided across the top 2 terminals or two on the front. The LC12/3-5 can provide 4 quadrant control of up to 130kW of power and the LC12/6-7 can provide up to 165kW in the same form factor.

DCDC-LC12/6 – EPC’s DCDC converter can provide up to 580kW of DC power per modules. The highly configureable unit is highly reliable for critical operations and has even eliminated internal fans for our liquid cooled units.

RS-11 & RS-12 – EPC’s automotive grade drivetrian inverters has been designed for IP67 environmental protection and thus can operate within up to 9 feet of water. The unit is ideal for Class 3 – Class 8 truck drivetrain controls.

V2G Export Power – EPC has packaged our MG-LC12/6, supporting grid filters, and coolant system into a single IP67 rated container. The product is built for Class 3 Utility Bucket Trucks but works well in marine or larger truck deployments.

Industrial Waste Water Blower Controller – 200kw DFE (Diode Front End)unidirectional motor drive for controlled blowers in a waste water treatment facility.

Centralized utility control systems are unable to respond to sub-cycle

local energy dynamics.

Grid management is shifting to automated real-time reactive

control of distributed systems with multiple owners.

Distributed Technology Enables the ‘Smart Grid’

10

Digital equipment acts as a “power gateway.” By processing power through converters, high-power systems become fully internet-addressable & computer-

controllable.

This both enables the smart grid and increases energy efficiency.

(Smart) inverters are the brain or voice of distributed systems.EPC Power’s systems are all “smart grid enabled” by design.
