STARplug, TEA1522, flyback, e-metering
The STARplug Switched Mode Power Supply (SMPS) for e-metering
application implements a power supply that can be used in combination
with all electricity utility networks worldwide i.e. single phase, two or three
phase (assuming 120º phase angle) 100 V, 110 V, 120 V, 220 V, 230 V and
240 V (AC) 20 % for each individual phase.
This manual describes the STARplug e-metering SMPS demo board
version 1.03. For details on the STARplug device please refer to the
TEA152x data sheet and for general application information refer to
STARplug application note AN00055.

STARplug e-metering SMPS connections 5. Circuit description The default STARplug e-metering SMPS circuit consists of a three-phase full-wave rectifier circuit, a filtering section, a primary switching section operating in flyback mode, two separate output sections, and a feedback section. Each of these circuit sections are described in Section 5.1... -
Page 7: Primary Switching Section
5.3 Primary switching section The primary switcher uses a standard TEA1522 STARplug IC and a cascading MOSFET Q1. This combination creates a hybrid STARplug solution with a virtual > 1.2 kV breakdown voltage MOSFET. The high breakdown voltage is necessary to be compatible with high voltage three-phase electricity utility networks. -
