2 / 15 page CBC-EVAL-09 EnerChip EP Universal EH Eval Kit ©2013 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-13 Rev G Page 2 of 15 EVAL-09 Block Diagram Explanations This section describes the EVAL-09 functional blocks shown in Figure 2. DC IN - Energy Harvesting transducer input below 4.06V DC. Normally a photovoltaic cell. AC IN - Energy Harvesting transducer input below 4.06V AC. An example might be an electromagnetic input from a flow harvester. HV DC IN - Energy Harvesting constant impedance transducer input from 4.06V DC to 20VDC. Normally a photovoltaic cell or higher voltage thermoelectric generator. HV AC1 IN and HV AC2 IN - Energy Harvesting transducer input from 4.06V DC to 20V AC. Normally a piezoelectric vibrational harvester. A single input can be utilized on HV AC1. If two piezo electric beams are mechanically coupled together in the same transducer unit, the two outputs can be connected to HV AC1 and HV AC2. Bridge Rectifiers - Rectifies from AC to DC for AC In or HV AC IN. Boost Converter - Boosts the DC In or AC IN voltage to 4.06 Volts. Low Voltage Charge Pumps (2) - Used to start up the CBC915 Energy Processor. Flyback Down Converter - Drop HV DC IN or HV AC1 IN/HV AC2 IN down to 4.06V. Energy Processor - EnerChip EP CBC915-AC Energy Processor finds the Maximum Peak Power Tracking point of the EH transducer input, To locate the version of the CBC915-AC device that is on the EVAL-09 look at the back of the EVAL-09 board on the label. A letter indicator of A, B, etc. will be found there which indicates CBC915-ACA, CBC915-ACB, etc. Functional details of each EnerChip EP version are documented in the Datasheet DS-72-15. Transducer Input Voltage Select and Sense Switches - Monitors all input voltages and connects to the Energy Processor. EnerChip CBC51100 Solid State Battery Module - Two EnerChip 50uAh solid state batteries (CBC3150 and CBC050) for energy storage. Low Voltage Cut-off - Should the voltage on the EnerChips fall below 3.0VDC, this circuit disconnects the batteries so they do not discharge further. Energy Management Switching Matrix - Controls the routing of Vout to the system load. User selectable switches indicate the EH transducer input to voltage output. Serial I/O - These 2 communications lines connect the Energy Processor to another microcontroller such as the TI MSP430 MCU on the eZ430-RF2500 demo kit wireless end device that would plug into connector J9. |
