After AC Rectification, the next step is Reducing the Ripple on the DC supply line as much as possible.

AC (Alternating Current) is used for the transmission of mains voltage, one of its main advantages for use as a method of transmission over DC (Direct Current) is that a change of voltage between High Voltage, Low Voltage, and SELV (Safety Extra-low Voltage) can be performed using a transformer. A […]
For the Charging Two EVs on One EVSE project, I will need a Vehicle Inlet ‘Male’ type EV charging connector for the upstream supply from the existing EVSE. And two EVSE ‘Female’ type EV connectors to allow for connection to the downstream vehicles, Since we are in the UK I […]
Like an increasing number of people, we have one home EV charger but have two EVs. My 2015 Nissan Leaf has a range of about 60 miles, which is perfect for daily school runs, and trips to the office. However, this means that most nights I need to put it […]
Following on from my quick overview of Proximity Pilot and Control Pilot, we will need to dig a little deeper into the functionality of CP/PP to talk about how to make some circuits for a minimalist EVSE (Electric Vehicle Supply Equipment). I would not recommend using this in production as […]
An EV emulator or EVSE test box is a device that you can use to test EVSE equipment. it allows you to change between different charge states and cable configurations. It will also allow you to draw current from EVSE equipment, as well as offering through normal valid states, An […]
One of the standard tests for EMC testing is ESD Testing, It is one of the tests worth doing first, so if you fail this test, you haven’t spent all that much time or money on testing. In most cases, you will be looking at “IEC 61000-4-2: Electromagnetic compatibility (EMC) […]
If I were to advise someone just starting in the field of EMC today, the advice I would give them would depend on what field they wanted to go into and their background. I didn’t plan to go into EMC testing or Engineering. I started at CASS Industries in 2014 […]
When I was working for ARRIVAL, setting up the Automotive EMC lab there, I needed an ISO 10605 Annex F island as part of the ESD test setup. This test setup is as far as I am aware unique to Automotive, and as such commercial EMC Technicians and Engineers are […]
On the 1st of August 2023 UK Government announced an indefinite extension to CE marking, the UK Government has stated that it intends to continue recognition of the CE mark indefinitely for most goods being placed on the market in Great Britain; this is a statement which revokes the previous […]
The main communications between Level 1 and 2 EVSE (Modes 2 and 3 and sometimes 4) and Electric Vehicles is via the Proximity Pilot and Control Pilot lines on the connectors. Level 1 (Mode 2) is portable charging equipment like an “In Cable Control Box” (ICCB) (commonly referred to as […]
This post is about the definitions in BS EN IEC 61851 Part 1 (2019) a standard called “Electric Vehicle Conductive Charging System, Part 1: General Requirements” These definitions are different to the terminology used normally when talking about charging speeds. I was reading through IEC 61851-1 to check something else […]
