Technology

Total Mobile Power inverter technology delivers:

Highly efficient inverters at low DC supply voltages
See efficiency curves

•  optimised for 24VDC but also suitable for 48V
•  prototype 24VDC to 230VAC inverter has greater than 95% efficiency from 270W to 4200W and a peak efficiency of 97.2% at 1500W
• ideally suited where there is an existing 24V supply (trucks, RVs, and boats),  for off grid houses  or for fuel cells.

Compact electronic power modules

• needs only DC input reservoir capacitors and an output PWM filter to make an inverter.
• current prototype capable of continuous output of 4kW at an ambient temperature of 40°C
• production versions will be capable of 5kW continuous and 8kW for 3 seconds
• form factor optimised for packing multiple modules into a single enclosure
• single power module size 100 x 140 x 280mm
• a 20kW inverter containing four power modules projected to be 440 x 540 x 230mm (w x h x d) and weigh less than 30kg.

Low no load power

• less than 9W for a 5kW inverter
• low power control electronics using a FPGA (Field Programmable Gate Array)
• low power innovative resonant gate drive technique (patent applied for)

DC to DC module also available

• high power (up to 5kW)
• bi-directional
• high step up ratio (e.g. 24V to 450V)
• highly efficient (greater than 97% at 5kW)
• compact
