App note: Performance comparison of 1200 V SiC MOSFET and Si IGBT Used in power integrated module for 1100 V solar boost stage

App note from ON Semiconductors comparing the performance between SiC MOSFET and Silicon IGBT in a similar and compatible power modules. Link here (PDF) This application note compares the performance of two power integrated modules (PIMs) in the boost stage of an 1100 V solar inverter. One PIM used state−of−the−art silicon 1200 V IGBT (part […]

App note: Grid-connected solar microinverter reference design

A good read from Microchip on the theory behind inverter design connected to grip power. Link here (PDF) There are two main requirements for solar inverter systems: harvest available energy from the PV panel and inject a sinusoidal current into the grid in phase with the grid voltage. In order to harvest the energy out […]

App note: On-grid solar microinverter on Freescale MC56F82xx/MC56F82xxx DSCs

Application note from Freescale Semiconductor about microinverter solution develop together with Future Electronics. Link here (PDF) In recent years, demand for renewable energy has increased significantly. The development of devices utilizing clean energy such as solar, wind, geothermal, and fuel cells attracts more and more attention. Solar energy harvesting is developing fast and will play […]

Open Inverter, an open source micro-solar inverter

Ken Boak has been working on an open source micro-solar inverter project: We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it can easily […]

Mastervolt soladin RF filtering

Brian Dorey writes: Following from the Mastervolt Soladin 600 Inverter RF Interference post about the major RF interference problems generated by the Mastervolt Soladin 600 tie-in mains inverter we have now resolved the RF interference by replacing the unscreened and unearthed plastic case on the inverter with an earthed metal case and installed filters on […]
