3 / 8 page CONFIGURATION The EHE004 has two means of signal rectification (Normal and Superseries) and two ways to connect the two piezoelectric wafers in a Volture™ product (Series and Parallel). There are also four options for the regulated DC output (1.8V, 2.5V, 3.3V, and 3.6V). In total there are sixteen possible configuration settings. The vibration environment and voltage requirements dictated by the application will determine the best configuration settings for the EHE004. Maximum Power Point: The efficiency of power transfer from the piezo to the load, and thus normalized power (mW/G), will be at maximum when the loaded piezo voltage (for moderate to heavy loads, equal to the average UVLO voltage) is approximately ½ its open-circuit voltage. However, the ouput will continue to increase with increasing vibration amplitude. For light loads where VCAP is not depleted to the UVLO voltage during buck operation, transfer efficiency is inconsequential as more power is available than the load can use. Normal vs. “Superseries”: The difference between ‘Normal’ and ‘Superseries’, is the bridge rectifier connection. In the normal mode of operation, the bridge rectifier is operated in fullbridge mode and its output voltage is half the peak-to-peak input voltage minus two diode drops. In the “superseries” configuration, the rectifier operates in a half-bridge mode with only one diode drop. The normal mode is recommended for maximum power output at moderate input voltages, however the halfbridge mode will allow operation from slightly lower minimum input voltages. Parallel vs. Series operation: All of MIDE’s Volture products contain two piezo elements stacked in a bimorph configuration and pinned out independently, allowing the user to choose between parallel and series connection. On the EHE004 board, switch SW1 selects between parallel (doubled current, lower input voltage) and series (doubled input voltage, lower current) connection. Generally low level vibrations are best suited to the series configuration and high level vibrations are best suited to the parallel configuration. However, the optimal setting will depend on a number of factors including which Volture product is being used and the parameters of the vibration environment. The table below shows the general configuration settings for different application types. However, each application is unique and the optimal settings will depend on both the application and Volture™ or other piezoelectric element used for the energy conversion. Table 1: General configuration guide listing for various applications. Every application is unique and may not fit these general settings. 3 REVISION N0. 002 REVISION DATE: 01-23-2013 EHE004 Application (Vibration Level) General EHE004 Configuration Settings SW1 SW3 Very Low Amplitude Series Superseries Low to Moderate Amplitude Series or Superseries Moderate Amplitude Parallel Normal High Amplitude Parallel Normal |
