Leading Change
ETM is committed to leading change towards alternative energy sources. ETM was the first company in the USA to offer incentives to encourage employees to order and purchase PHEVs (plug-in hybrid electric vehicles).

ETM CEO Tom Hayse represents ETM’s membership in the Silicon Valley Leadership Group (SVLG), and actively represented the SVLG’s partnership with
Plug-In Bay Area (PIBA) to promote the commercialization of plug-in hybrid vehicles, beginning with the SVLG’s fleet order for PHEVs.

Actions speak louder than words every day at ETM.

Alternative Energy, Power Conversion, Grid-Tied Inverters
Tailored power conversion is at the core of every ETM product, in all permutations of voltage, current, power, AC and DC.

ETM has developed tailored, grid-tied inverters at the 250kW and 500kW scale for use in alternative energy applications. Field performance is excellent. The designs are modular and highly suitable for tailoring to any customer’s specific requirement. The products operate from -25C to +50C with no degradation in power. The dual processor (FPGA/DSP) control electronics uniquely separate safety functions from switching control and communications.
